2.1 Commutators and the Lower Central Series
The commutator of two elements h_1 and h_2 of a group G is the element h_1^-1h_2^-1h_1h_2 and is denoted by [h_1,h_2]. It satisfies the equation h_1h_2 = h_2h_1[h_1,h_2] and can be interpreted as the correction term that has to be introduced into a word if two elements of a group are interchanged. Iterated commutators are written in left-normed fashion: [h_1,h_2,...,h_n-1,h_n]=[[h_1,h_2,...,h_n-1],h_n].
The lower central series of G is defined inductively as γ_1(G) = G, γ_i(G) = [γ_i-1(G),G] for i ge 2. Each term in the lower central series is a normal (even fully invariant) subgroup of G. The factors of the lower central series are abelian groups. On each factor the induced action of G via conjugation is the trivial action.
The factor γ_k(G)/γ_k+1(G) is generated by the elements [g,h]γ_k+1(G), where g runs through a set of (representatives of) generators for G/γ_2(G) and h runs through a set of (representatives of) generators for γ_k-1(G)/γ_k(G). Therefore, each factor of the lower central series is finitely generated if G is finitely generated.
If one factor of the lower central series is finite, then all subsequent factors are finite. Then the exponent of the k+1-th factor is a divisor of the exponent of the k-th factor of the lower central series. In particular, the exponents of all factors of the lower central series are bounded by the exponent of the first finite factor of the lower central series.
2.2 Nilpotent groups
A group G is called nilpotent if there is a positive integer c such that all (c+1)-fold commutators are trivial in G. The smallest integer with this property is called the nilpotency class of G. In terms of the lower central series a group G not= 1 has nilpotency class c if and only if γ_c(G) not= 1 and γ_c+1(G) = 1.
Examples of nilpotent groups are finite p-groups, the group of unitriangular matrices over a ring with one and the factor groups of a free group modulo the terms of its lower central series.
Finiteness of a nilpotent group can be decided by the group's commutator factor group. A nilpotent group is finite if and only if its commutator factor group is finite. A group whose commutator factor group is finite can only have finite nilpotent quotient groups.
By refining the lower central series of a finitely generated nilpotent group one can obtain a (sub)normal series G_1>G_2>...>G_k+1=1 with cyclic (central) factors. Therefore, every finitely generated nilpotent group is polycyclic. Such a polycyclic series gives rise to a polycyclic generating sequence by choosing a generator a_i for each cyclic factor G_i/G_i+1. Let I be the set of indices such that G_i/G_i+1 is finite. A simple induction argument shows that every element of the group can be written uniquely as a normal worda_1^e_1... a_n^e_n with integers e_i and 0≤ e_i<m_i for i∈ I.
2.3 Nilpotent presentations
From a polycyclic generating sequence one can obtain a polycyclic presentation for the group. The following set of power and commutator relations is a defining set of relations. The power relations express a_i^m_i in terms of the generators a_i+1,...,a_n whenever G_i/G_i+1 is finite with order m_i. The commutator relations are obtained by expressing [a_j,a_i] for j>i as a word in the generators a_i+1,...,a_n. If the polycyclic series is obtained from refining the lower central series, then [a_j,a_i] is even a word in a_j+1,...,a_n. In this case we obtain a nilpotent presentation.
To be more precise, a nilpotent presentation is given on a finite number of generators a_1,...,a_n. Let I be the set of indices such that G_i/G_i+1 is finite. Let m_i be the order of G_i/G_i+1 for i∈ I. Then a nilpotent presentation has the form
\langle a,\ldots,a_n |
a_i^{m_i} = w_{ii}(a_{i+1},\ldots,a_n)
\mbox{ for } i\in I;\;
[a_j,a_i] = w_{ij}(a_{j+1},\ldots,a_n)
\mbox{ for } 1\leq i < j\leq n\rangle
Here, w_ij(a_k,...,a_n) denotes a group word in the generators a_k,...,a_n.
In a group given by a polycyclic presentation each element in the group can be written as a normal worda_1^e_1... a_n^e_n with e_i ∈ Z and 0 ≤ e_i < m_i for i ∈ I. A procedure called collection can be used to convert an arbitrary word in the generators into an equivalent normal word. In general, the resulting normal word need not be unique. The result of collecting a word may depend on the steps chosen during the collection procedure. A polycyclic presentation with the property that two different normal words are never equivalent is called consistent. A polycyclic presentation derived from a polycyclic series as above is consistent. The following example shows an inconsistent polycyclic presentation
\langle a,b\mid a^2, b^a = b^2 \rangle
as b = baa = ab^2a = a^2b^4 = b^4 which implies b^3=1. Here we have the equivalent normal words b^3 and the empty word. It can be proved that consistency can be checked by collecting a finite number of words in the given generating set in two essentially different ways and checking if the resulting normal forms are the same in both cases. See Chapter 9 of the book [Sim94] for an introduction to polycyclic groups and polycyclic presentations.
For computations in a polycyclic group one chooses a consistent polycyclic presentation as it offers a simple solution to the word problem: Equality between two words is decided by collecting both words to their respective normal forms and comparing the normal forms. Nilpotent groups and nilpotent presentations are special cases of polycyclic groups and polycyclic presentations. Nilpotent presentations allow specially efficient collection methods. The package Polycyclic provides algorithms to compute with polycyclic groups given by a polycyclic presentation.
However, inconsistent nilpotent presentations arise naturally in the nilpotent quotient algorithm. There is an algorithm based on the test words for consistency mentioned above to modify the arising inconsistent presentations suitably to obtain a consistent one for the same group.
2.4 A sketch of the algorithm
The input for the ANU NQ in its simplest form is a finite presentation ⟨ X|R⟩ for a group G. The first step of the algorithm determines a nilpotent presentation for the commutator quotient of G. This is a presentation of the class-1 quotient of G. Call its generators a_1,...,a_d. It also determines a homomorphism of G onto the commutator quotient and describes it by specifying the image of each generator in X as a word in the a_i.
For the general step assume that the algorithm has computed a nilpotent presentation for the class-c quotient of G and that a_1,...,a_d are the generators introduced in the first step of the algorithm. Furthermore, there is a map from X into the class-c quotient describing the epimorphism from G onto G/γ_c+1(G).
Let b_1,...b_k be the generators from the last step of the algorithm, the computation of γ_c(G)/γ_c+1(G). This means that b_1,...b_k generate γ_c(G)/γ_c+1(G). Then the commutators [b_j,a_i] generate γ_c+1(G)/γ_c+2(G). The algorithm introduces new, central generators c_ij into the presentation, adds the relations [b_j,a_i] = c_ij and modifies the existing relations by appending suitable words in the c_ij, called tails, to the right hand sides of the power and commutator relations. The resulting presentation is a nilpotent presentation for the nilpotent cover of G/γ_c+1(G). The nilpotent cover is the largest central extension of G/γ_c+1(G) generated by d elements. It is is uniquely determined up to isomorphism.
The resulting presentation of the nilpotent cover is in general inconsistent. Consistency is achieved by running the consistency test. This results in relations among the generators c_ij which can be used to eliminate some of those generators or introduce power relations. After this has been done we have a consistent nilpotent presentation for the nilpotent cover of G/γ_c+1(G).
Furthermore, the nilpotent cover need not satisfy the relations of G. In other words, the epimorphism from G onto G/γ_c+1(G) cannot be lifted to an epimorphism onto the nilpotent cover. Applying the epimorphism to each relator of G and collecting the resulting words of the nilpotent cover yields a set of words in the c_ij. This gives further relations between the c_ij which leads to further eliminations or modifications of the power relations for the c_ij.
After this, the inductive step of the ANU NQ is complete and a consistent nilpotent presentation for G/γ_c+2(G) is obtained together with an epimorphism from G onto the class-(c+1) quotient.
Chapter 11 of the book [Sim94] discusses a nilpotent quotient algorithm. A description of the implementation in the ANU NQ is contained in [Nic96]
2.5 Identical Relations
Let w be a word in free generators x_1,...,x_n. A group G satisfies the relation w=1identically if each map from x_1,...,x_n into G maps w to the identity element of G. We also say that G satisfies the identical relationw=1 or satisfies the laww=1. In slight abuse of notation, we call the elements x_1,...,x_nidentical generators.
Common examples of identical relations are: A group of nilpotency class at most c satisfies the law [x_1,...,x_c+1]=1. A group that satisfies the law [x,y,...,y]=1 where y occurs n-times, is called an n-Engel group. A group that satisfies the law x^d=1 is a group of exponent d.
To describe finitely presented groups that satisfy one or more laws, we extend a common notation for finitely presented groups by specifying the identical generators as part of the generator list, separated from the group generators by a semicolon: For example
\langle a,b,c; x,y | x^5, [x,y,y,y]\rangle
is a group on 3 generators a,b,c of exponent 5 satisfying the 3rd Engel law. The presentation above is equivalent to a presentation on 3 generators with an infinite set of relators, where the set of relators consists of all fifth powers of words in the generators and all commutators [x,y,y,y] where x and y run through all words in the generators a,b,c. The standalone programme accepts the notation introduced above as a description of its input. In GAP 4 finitely presented groups are specified in a different way, see NilpotentQuotient (3.1-1) for a description.
This notation can also be used in words that mix group and identical generators as in the following example:
\langle a,b,c; x | [x,c], [a,x,x,x] \rangle
The first relator specifies a law which says that c commutes with all elements of the group. The second turns a into a third right Engel element.
An element a is called a right n-th Engel element or a right n-Engel element if it satisfies the commutator law [a,x,...,x]=1 where the identical generator x occurs n-times. Likewise, an element b is called an left n-th Engel element or left n-Engel element if it satisfies the commutator law [x,b,b,...b]=1.
Let G be a nilpotent group. Then G satisfies a given law if the law is satisfied by a certain finite set of instances given by Higman's Lemma, see [Hig59]. The ANU NQ uses Higman's Lemma to obtain a finite presentation for groups that satisfy one or several identical relations.
2.6 Expression Trees
Expressions involving commutators play an important role in the context of nilpotent groups. Expanding an iterated commutator produces a complicated and long expression. For example,
[x,y,z] = y^{-1}x^{-1}yxz^{-1}x^{-1}y^{-1}xyz.
Evaluating a commutator [a,b] is done efficiently by computing the equation (ba)^-1ab. Therefore, for each commutator we need to perform two multiplications and one inversion. Evaluating [x,y,z] needs four multiplications and two inversions. Evaluation of an iterated commutator with n components takes 2n-1 multiplications and n-1 inversions. The expression on the right hand side above needs 9 multiplications and 5 inversions which is clearly much more expensive than evaluating the commutator directly.
Assuming that no cancellations occur, expanding an iterated commutator with n components produces a word with 2^n+1-2^n-1-2 factors half of which are inverses. A similar effect occurs whenever a compact expression is expanded into a word in generators and inverses, for example (ab)^49.
Therefore, it is important not to expand expressions into a word in generators and inverses. For this purpose we provide a mechanism which we call here expression trees. An expression tree preserves the structure of a given expression. It is a (binary) tree in which each node is assigned an operation and whose leaves are generators of a free group or integers. For example, the expression [(xy)^2, z] is stored as a tree whose top node is a commutator node. The right subtree is just a generator node (corresponding to z). The left subtree is a power node whose subtrees are a product node on the left and an integer node on the right. An expression tree can involve products, powers, conjugates and commutators. However, the list of available operations can be extended.
Evaluation of an expression tree is done recursively and requires as many operations as there are nodes in the tree. An expression tree can be evaluated in a specific group by the function EvaluateExpTree (3.2-2).
A presentation specified by expression trees is a record with the components .generators and .relations. See section 3.2 for a description of the functions that produce and manipulate expression trees.
The ANU NQ is written in C, but not in ANSI C. I hope to make one of the next versions ANSI compliable. However, it uses a fairly restricted subset of the language so that it should be easy to compile it in new environments. The code is 64-bit clean. If you have difficulties with porting it to a new environment, let me know and I'll be happy to assist if time permits.
The program has two collectors: a simple collector from the left as described in [LGS90] and a combinatorial from the left collector as described in [VL90]. The combinatorial collector is always faster than the simple collector, therefore, it is the collector used by this package by default. This can be changed by modifying the global variable NqDefaultOptions (3.4-2).
In a polycyclic group with generators that do not have power relations, exponents may become arbitrarily large. Experience shows that this happens rarely in the computations done by the ANU NQ. Exponents are represented by 32-bit integers. The collectors perform an overflow check and abort the computation if an overflow occurred. In a GNU environment the program can be compiled using the `long long' 64-bit integer type. For this uncomment the relevant line in src/Makefile and recompile the program.
As part of the step that enforces consistency and the relations of the group, the ANU NQ performs computations with integer matrices and converts them to Hermite Normal Form. The algorithm used here is a variation of the Kanan-Bachem algorithm based on the GNU multiple precision package GNU MP [GMP]. Experience shows that the integer matrices are usually fairly sparse and Kanan-Bachem seems to be sufficient in this context. However, the implementation might benefit from a more efficient strategy for computing Hermite Normal Forms. This is a topic for further investigations.
As the program does not compute the Smith Normal Form for each factor of the lower central series but the Hermite Normal Form, it does not necessarily obtain a minimal generating set for each factor of the lower central series. The following is a simple example of this behaviour. We take the presentation
\langle x, y | x^2 = y \rangle
The group is clearly isomorphic to the additive group of the integers. Applying the ANU NQ to this presentation gives the following nilpotent presentation:
\langle A,B | A^2 = B, [B,A] \rangle
A nilpotent presentation on a minimal generating set would be the presentation of the free group on one generator:
\langle A | \; \rangle
2.8 The input format of the standalone
The input format for finite presentations resembles the way many people write down a presentation on paper. Here are some examples of presentations that the ANU NQ accepts:
< a, b | > # free group of rank 2
< a, b, c; x, y |
[a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation
(a*[b,(a*c)])^6, # something that looks complicated
[x,y,y,y,y], # an identical relation
[c,x,x,x,x,x] # c is a fifth right Engel element
>
A presentation starts with '<' followed by a list of generators separated by commas. Generator names are strings that contain only upper and lower case letters, digits, dots and underscores and that do not start with a digit. The list of generator names is separated from the list of relators/relations by the symbol '∣'. The list of generators can be followed by a list of identical generators separated by a semicolon. Relators and relations are separated by commas and can be mixed arbitrarily. Parentheses can be used in order to group subexpressions together. Square brackets can be used in order to form left normed commutators. The symbols '*' and '^' can be used to form products and powers, respectively. The presentation finishes with the symbol '>'. A comment starts with the symbol '#' and finishes at the end of the line. The file src/presentation.c contains a complete grammar for the presentations accepted by the ANU NQ.
Typically, the input for the standalone is put into a file by using a standard text editor. The file can be passed as an argument to the function NilpotentQuotient (3.1-1). It is also possible to put a presentation in the standalone's input format into a string and use the string as argument for NilpotentQuotient (3.1-1).

Installation of the Package
Installation of the ANU NQ is done in two steps.
Configuring for compilation
First the configure script is run:
./configure
If you installed the package in another pkg directory than
the standard pkg directory in your &GAP; 4 installation,
then you have to do two things. Firstly during compilation you have to
use the option --with-gaproot=PATH of the configure script
where PATH is a path to the main &GAP; root directory (if not
given the default ../.. is assumed). That is, run
./configure --with-gaproot=PATH
Secondly you have to specify the path to the directory containing your
pkg directory to &GAP;'s list of directories. This can be
done by starting &GAP; with the -l command line option
followed by the name of the directory and a semicolon. Then your
directory is prepended to the list of directories searched. Otherwise
the package is not found by &GAP;. Of course, you can add this option to
your &GAP; startup script.
Another issue that can occur when running configure is that it
may fail to locate the the GNU multiple precision library (GMP
) which ANU NQ requires to work. This library is also
used by &GAP; and hence normally should be available on your system
anyway. But if this is not the case for some reason, it has to be
installed first. A copy of GMP can be obtained from
http://gmplib.org/.
In order for the configure script to find your copy of GMP, you
may have tell it where to find it via --with-gmp=PATH, where
PATH is the path where GMP was installed:
./configure --with-gmp=PATH
Yf necessary, you may combine --with-gmp and
--with-gaproot.
Compiling the nq binary
If configure reports no problems, the next step is to start the
compilation:
make
A compiled version of the program named nq is then placed
into the directory bin/&tlt;complicated name&tgt;. The
&tlt;complicated name&tgt; component encodes the operating system
and the compiler used. This allows you to compile NQ on several
architectures sharing the same files system.
If there are any warnings or even fatal error messages during the
compilation process, please submit a bug report about that
following the instructions in Section Testing
After the compilation is finished you can check if the ANU NQ
is running properly on your system. Simply type
make test
This runs some computations and compares their output with the output
files in the directory examples. If any errors are reported, please
follow the instructions below.
Feedback
If you encounter problems with any of the above steps, please do not
hesitate to contact us about this. You can either use the
https://github.com/gap-system/nq/issues
or contact the GAP support group via support@gap-system.org.
Please make sure to include information about the specific issue
you encountered (e.g. steps to reproduce it, the specific error message),
your operating system, the compiler you used
and also the versions of &GAP; and this package that were involved.

GAP (nq) - Chapter 3: The Functions of the Package
The parameter fp-group is either a finitely presented group or a record specifying a presentation by expression trees (see section 2.6). The parameter input-file is a string specifying the name of a file containing a finite presentation in the input format (cf. section 2.8) of the ANU NQ. Such a file can be prepared by a text editor or with the help of the function NqStringFpGroup (3.3-2).
Let G be the group defined by fp-group or the group defined in input-file. The function computes a nilpotent presentation for G/γ_c+1(G) if the optional parameter c is specified. If c is not given, then the function attempts to compute the largest nilpotent quotient of G and it will terminate only if G has a largest nilpotent quotient. See section 3.5 for a possibility to follow the progress of the computation.
The optional argument id-gens is a list of generators of the free group underlying the finitely presented group fp-group. The generators in this list are treated as identical generators. Consequently, all relations of the fp-group involving these generators are treated as identical relations for these generators.
In addition to the arguments explained above, the function accepts the following options as shown in the first example below:
group This option can be used instead of the parameter fp-group.
input\_string This option can be used to specify a finitely presented group by a string in the input format of the standalone program.
input\_file This option specifies a file with input for the standalone program.
output\_file This option specifies a file for the output of the standalone.
idgens This options specifies a list of identical generators.
class This option specifies the nilpotency class up to which the nilpotent quotient will be computed.
The following example computes the class-5 quotient of the free group on two generators.
gap>F := FreeGroup( 2 );
<free group on the generators [ f1, f2 ]>
gap>## Equivalent to: NilpotentQuotient( : group := F, class := 5 );gap>## NilpotentQuotient( F : class := 5 ); gap>H := NilpotentQuotient( F, 5 );
Pcp-group with orders [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
gap>lcs := LowerCentralSeries( H );;gap>for i in [1..5] do Print( lcs[i] / lcs[i+1], "\n" ); od;
Pcp-group with orders [ 0, 0 ]
Pcp-group with orders [ 0 ]
Pcp-group with orders [ 0, 0 ]
Pcp-group with orders [ 0, 0, 0 ]
Pcp-group with orders [ 0, 0, 0, 0, 0, 0 ]
Note that the lower central series in the example is part of the data returned by the standalone program. Therefore, the execution of the function LowerCentralSeries takes no time.
The next example computes the class-4 quotient of the infinite dihedral group. The group is soluble but not nilpotent. The first factor of its lower central series is a Klein four group and all the other factors are cyclic or order 2.
gap>F := FreeGroup( 2 );
<free group on the generators [ f1, f2 ]>
gap>G := F / [F.1^2, F.2^2];
<fp group on the generators [ f1, f2 ]>
gap>H := NilpotentQuotient( G, 4 );
Pcp-group with orders [ 2, 2, 2, 2, 2 ]

In the following example identical generators are used in order to express the fact that the group is nilpotent of class 3. A group is nilpotent of class 3 if it satisfies the identical relation [x_1,x_2,x_3,x_4]=1 (cf. Section 2.5). The result is the free nilpotent group of class 3 on two generators.
gap>F := FreeGroup( "a", "b", "w", "x", "y", "z" );
<free group on the generators [ a, b, w, x, y, z ]>
gap>G := F / [ LeftNormedComm( [F.3,F.4,F.5,F.6] ) ];
<fp group of size infinity on the generators [ a, b, w, x, y, z ]>
gap>## The following is equivalent to: gap>## NilpotentQuotient( G : idgens := [F.3,F.4,F.5,F.6] );gap>H := NilpotentQuotient( G, [F.3,F.4,F.5,F.6] );
Pcp-group with orders [ 0, 0, 0, 0, 0 ]
gap>NilpotencyClassOfGroup(H);

gap>LowerCentralSeries(H);
[ Pcp-group with orders [ 0, 0, 0, 0, 0 ], Pcp-group with orders [ 0, 0, 0 ],
Pcp-group with orders [ 0, 0 ], Pcp-group with orders [ ] ]
The following example uses expression trees in order to specify the third Engel law for the free group on 3 generators.
The example above also shows that the relative orders of an abelian polycyclic group need not be the abelian invariants (elementary divisors) of the group. Each zero corresponds to a generator of infinite order. The number of zeroes is always correct.
This function is a special version of NilpotentQuotient (3.1-1) which enforces the n-th Engel identity on the nilpotent quotients of the group specified by fp-group or by input-file. It accepts the same options as NilpotentQuotient.
The Engel condition can also be enforced by using identical generators and the Engel law and NilpotentQuotient (3.1-1). See the examples there.
The following example computes the relatively free fifth Engel group on two generators, determines its (normal) torsion subgroup and computes the corresponding quotient group. The quotient modulo the torsion subgroup is torsion-free. Therefore, there is a nilpotent presentation without power relations. The example computes a nilpotent presentation for the torsion free factor group through the upper central series. The factors of the upper central series in a torsion free group are torsion free. In this way one obtains a set of generators of infinite order and the resulting nilpotent presentation has no power relations.
This function computes an epimorphism from the group G given by the finite presentation fp-group onto G/γ_c+1(G). If c is not given, then the largest nilpotent quotient of G is computed and an epimorphism from G onto the largest nilpotent quotient of G. If G does not have a largest nilpotent quotient, the function will not terminate if c is not given.
The optional argument id-gens is a list of generators of the free group underlying the finitely presented group fp-group. The generators in this list are treated as identical generators. Consequently, all relations of the fp-group involving these generators are treated as identical relations for these generators.
If identical generators are specified, then the epimorphism returned maps the group generated by the `non-identical' generators onto the nilpotent factor group. See the last example below.
The function understands the same options as the function NilpotentQuotient (3.1-1).
gap>F := FreeGroup(3);
<free group on the generators [ f1, f2, f3 ]>
gap>phi := NqEpimorphismNilpotentQuotient( F, 5 );

Note that the last epimorphism is a map from the group generated by a and b onto the nilpotent quotient. The identical generators are used only to formulate the identical relator. They are not generators of the group G. Also note that the left-normed commutator above is mapped to the identity as G satisfies the specified identical law.
3.1-4 LowerCentralFactors
‣ LowerCentralFactors( ... )
( function )
This function accepts the same arguments and options as NilpotentQuotient (3.1-1) and returns a list containing the abelian invariants of the central factors in the lower central series of the specified group.
The argument m must be a positive integer. The function returns a list with m expression tree symbols named x1, x2,... The optional parameter prefix must be a string and is used instead of x if present.
Alternatively, the function can be executed with a list of strings str1, str2, .... It returns a list of symbols with these strings as names.
The following operations are defined for expression trees: multiplication, inversion, exponentiation, forming commutators, forming conjugates.
gap>t := ExpressionTrees( 3 );

3.2-2 EvaluateExpTree
‣ EvaluateExpTree( tree, symbols, values )
( function )
The argument tree is an expression tree followed by the list of those symbols symbols from which the expression tree is built up. The argument values is a list containing a constant for each symbol.

3.3 Auxiliary Functions
3.3-1 NqReadOutput
‣ NqReadOutput( stream )
( function )
The only argument stream is an output stream of the ANU NQ. The function reads the stream and returns a record that has a component for each global variable used in the output of the ANU NQ, see NqGlobalVariables (3.4-3).
3.3-2 NqStringFpGroup
‣ NqStringFpGroup( fp-group[, idgens] )
( function )
The function takes a finitely presented group fp-group and returns a string in the input format of the ANU NQ. If the list idgens is present, then it must contain generators of the free group underlying the finitely presented group FreeGroupOfFpGroup (Reference: FreeGroupOfFpGroup). The generators in idgens are treated as identical generators.

Pcp-group with orders [ 7, 7, 7 ]
3.3-3 NqStringExpTrees
‣ NqStringExpTrees( fp-group[, idgens] )
( function )
The function takes a finitely presented group fp-group given in terms of expression trees and returns a string in the input format of the ANU NQ. If the list idgens is present, then it must contain a sublist of the generators of the presentation. The generators in idgens are treated as identical generators.
The function ElementaryDivisorsMat (Reference: ElementaryDivisorsMat) only returns the non-zero elementary divisors of an integer matrix. This function computes the elementary divisors of int-mat and adds the appropriate number of zeroes in order to make it easier to recognize the isomorphism type of the abelian group presented by the integer matrix. At the same time ones are stripped from the list of elementary divisors.
3.4 Global Variables
3.4-1 NqRuntime
‣ NqRuntime
( global variable )
This variable contains the number of milliseconds of runtime of the last call of ANU NQ.
This variable contains a list of strings which are the standard command line options passed to the ANU NQ in each call. Modifying this variable can be used to pass additional options to the ANU NQ.
gap>NqDefaultOptions;
[ "-g", "-p", "-C", "-s" ]
The option -g causes the ANU NQ to produce output in GAP-format. The option -p prevents the ANU NQ from listing the pc-presentation of the nilpotent quotient at the end of the calculation. The option -C invokes the combinatorial collector. The option -s is effective only in conjunction with options for computing with Engel identities and instructs the ANU NQ to use only semigroup words in the generators as instances of an Engel law.
3.4-3 NqGlobalVariables
‣ NqGlobalVariables
( global variable )
This variable contains a list of strings with the names of the global variables that are used in the output stream of the ANU NQ. While the output stream is read, these global variables are assigned new values. To avoid overwriting these variables in case they contain values, their contents is saved before reading the output stream and restored afterwards.
3.5 Diagnostic Output
While the standalone program is running it can be asked to display progress information. This is done by setting the info class InfoNQ to 1 via the function SetInfoLevel (Reference: InfoLevel).

This package provides an interface between GAP 4 and the Australian National University Nilpotent Quotient Program (ANU NQ). The ANU NQ was implemented as part of the author's work towards his PhD at the Australian National University, hence the name of the program. The program takes as input a finite presentation of a group and successively computes factor groups modulo the terms of the lower central series of the group. These factor groups are computed in terms of polycyclic presentations.
The ANU NQ is implemented in the programming language C. The implementation has been developed in a Unix environment and Unix is currently the only operating system supported. It runs on a number of different Unix versions, e.g. Solaris and Linux.
For integer matrix computations it relies on the GNU MP [GMP] package and requires this package to be installed on your system.
This package relies on the functionality for polycyclic groups provided by the GAP package polycyclic[EN02] and requires the package polycyclic to be installed as a GAP package on your computer system.
Comments, bug reports and suggestions are very welcome, please submit them via our issue tracker.
This manual contains references to parts of the GAP Reference Manual which are typeset in a slightly idiosyncratic way. The following example shows how such references are printed: 'For further information on creating a free group see FreeGroup (Reference: FreeGroup).' The text in bold face refers to the GAP Reference Manual.
Each item in the list of references at the end of this manual is followed by a list of numbers that specify the pages of the manual where the reference occurs.
All parameters in square brackets are optional. The parameter <presentation> has to be the name of a file that contains a finite group presentation for which a nilpotent quotient is to be calculated. This file name must not start with a digit. If it is not present, nq will read the presentation from standard input. The parameter <class> restricts the computation of the nilpotent quotient to at most that (nilpotency) class, i.e. the program calculates the quotient group of the \((c+1)\)-th term of the lower central series. If <class> is omitted, the program computes successively the factor groups of the lower central series of the given group. If there is a largest nilpotent quotient, i.e., if the lower central series becomes constant, the program will eventually terminate with the largest nilpotent quotient. If there is no largest nilpotent quotient, the program will run forever (or more precisely will run out of resources). On termination the program prints a nilpotent presentation for the nilpotent quotient it has computed. The options -l, -r and -e can be used to enforce Engel conditions on the nilpotent quotient to be calculated. All these options have to be followed by a positive integer <n>. Their meaning is the following:
-n <k>
This option forces the first k generators to be left or right Engel element if also the option -l or -r (or both) is present. Otherwise it is ignored.
-l <n>
This forces the first k generators \(g_1,...,g_k\) of the nilpotent quotient Q to be left n-Engel elements, i.e., they satisfy \([x,...,x,g_i] = 1\) (x occurring n-times) for all x in Q and \(1 <= i <= k\). If the option -n is not used, then k = 1.
-r <n>
This forces the first k generators \(g_1,...,g_k\) of the nilpotent quotient Q to be right n-Engel elements,i.e., they satisfy \([g_i,x,..,x] = 1\) (x occurring n-times) for all x in Q and \(1 <= i <= k\). If the option -n is not used, then k = 1.
-e <n>
This enforces the n-th Engel law on Q, i.e., \([x,y,..,y] = 1\) (y occurring n-times) for all x,y in Q.
-t <n>
This option specifies how much CPU time the program is allowed to use. It will terminate after <n> seconds of CPU time. If <n> is followed (without space) by one of the letters m, h or d, <n> specifies the time in minutes, hours or days, respectively.
The other options have the following meaning. Care has to be taken when the options -s or -c are used since the resulting nilpotent quotient need NOT satisfy the required Engel condition. The reason for this is that a smaller set of test words is used if one of these two options are present. Although this smaller set of test words seems to be sufficient to enforce the required Engel condition, this fact has not been proven.
-a
For each factor of the lower central series a file is created in the current directory that contains an integer matrix describing the factor as abelian group. The first number in that file is the number of columns of the matrix. Then the matrix follows in row major order. The matrix for the i-th factor is put into the file <presentation>.abinv.<i>.
-p
toggles printing of the pc presentation for the nilpotent quotient at the end of a calculation.
-s
This option causes the program to check only semigroup words in the generating set of the nilpotent quotient when an Engel condition is enforced. If none of the options -l, -r or -e are present, it is ignored.
-f
This option causes to check semiwords in the generating set of the nilpotent quotient first and then all other words that need to be checked. It is ignored if the option -s is used or none of the options -l, -r or -e are present.
-c
This option stops checking the Engel law at each class if all the checks of a certain weight did not yield any non-trivial instances of the law.
-d
Switch on debug mode and perform checks during the computation. Not yet implemented.
-o
In checking Engel identities, instances are process in the order of increased weight. This flag reverses the order.
-y
Enforce the identities \(x^8\) and \([ [x1,x2,x3], [x4,x5,x6] ]\) on the nilpotent quotient.
-v
Switch on verbose mode.
-g
Produce GAP output. Presently the GAP output consists only of a sequence of integer matrices whose rows are relations of the factors of the lower central series as abelian groups. This will change as soon as GAP can handle infinite polycyclic groups.
-E
the *last* n generators are Engel generators. This works in conjunction with option -n.
-m
output the relation matrix for each factor of the lower central series. The matrices are written to files with the names 'matrix.<cl>' where <cl> is replaced by the number of the factor in the lower central series. Each file contains first the number of columns of the matrix and then the rows of the matrix. The matrix is written as each relation is produced and is not in upper triangular form.
-M
output the relation matrix before and after relations have been enforced. This results in two groups of files with names '<pres>.nilp.<cl>' and '<pres>.mult.<cl>' where <pres> is the name of the input files and <cl> is the class. The matrices are in upper triangular form.
A.2 The input format for presentations
The input format for finite presentations resembles the way many people write down a presentation on paper. Here are some examples of presentations that the ANU NQ accepts:
< a, b | > # free group of rank 2
< a, b, c | [a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation
(a*[b,(a*c)])^6 # something that looks complicated
>
A presentation starts with '<' followed be a list of generators separated by commas. Generator names are strings that contain only upper and lower case letters, digits, dots and underscores and that do not start with a digit. The list of generator names is separated from the list of relators/relations by the symbol '|'. Relators and relations are separated by commas and can be mixed arbitrarily. Parentheses can be used in order to group subexpressions together. Square brackets can be used in order to form left normed commutators. The symbols '*' and '^' can be used to form products and powers, respectively. The presentation finishes with the symbol '>'. A comment starts with the symbol '#' and finishes at the end of the line. The file src/presentation.c contains a complete grammar for the presentations accepted by the ANU NQ.
A.3 An example
Let G be the free group on two generators x and y. The input file (called free2.fp here) contains the following:
< x, y | >

Most of the comments are fairly self-explanatory. One note of caution is necessary: The number of generators for each factor of the lower central series is not the minimal number possible but is the number of generators that the ANU NQ chose to use. This will be improved in one of the future version of the program. The epimorphism from the original group onto the nilpotent quotient is printed in a somewhat confusing way. The generators on the left hand side of the arrows correspond to the generators in the original presentation but are printed with different names. This will be fixed in one of the next version.
A.4 Some remarks about the algorithm
The implementation of the algorithm is fairly straight forward. The program uses a weighted nilpotent presentation with definitions to represent a nilpotent group. Calculations in the nilpotent group are done using a collector from the left without combinatorial collection. Generators for the \(c\)-th lower central factor are defined as commutators of the form \([y,x]\), where \(x\) is a generator of weight 1 and \(y\) is a generator of weight \(c-1\). Then the program calculates the necessary changes (tails) for all relations which are not definitions, runs through the consistency check and evaluates the original relations on the polycyclic presentation. This gives a list of words, which have to be made trivial in order to obtain a consistent polycyclic presentation representing a nilpotent quotient of the given finitely presented group. This list is converted into a integer matrix, which is transformed into upper triangular form using the Kannan-Bachem algorithm. The GNU multiple precision package is used for this.
The parameter fp-group is either a finitely presented group or a record specifying a presentation by expression trees (see section 2.6). The parameter input-file is a string specifying the name of a file containing a finite presentation in the input format (cf. section 2.8) of the ANU NQ. Such a file can be prepared by a text editor or with the help of the function NqStringFpGroup (3.3-2).
Let \(G\) be the group defined by fp-group or the group defined in input-file. The function computes a nilpotent presentation for \(G/\gamma_{c+1}(G)\) if the optional parameter c is specified. If c is not given, then the function attempts to compute the largest nilpotent quotient of \(G\) and it will terminate only if \(G\) has a largest nilpotent quotient. See section 3.5 for a possibility to follow the progress of the computation.
The optional argument id-gens is a list of generators of the free group underlying the finitely presented group fp-group. The generators in this list are treated as identical generators. Consequently, all relations of the fp-group involving these generators are treated as identical relations for these generators.
In addition to the arguments explained above, the function accepts the following options as shown in the first example below:
group This option can be used instead of the parameter fp-group.
input\_string This option can be used to specify a finitely presented group by a string in the input format of the standalone program.
input\_file This option specifies a file with input for the standalone program.
output\_file This option specifies a file for the output of the standalone.
idgens This options specifies a list of identical generators.
class This option specifies the nilpotency class up to which the nilpotent quotient will be computed.
The following example computes the class-5 quotient of the free group on two generators.
gap>F := FreeGroup( 2 );
<free group on the generators [ f1, f2 ]>
gap>## Equivalent to: NilpotentQuotient( : group := F, class := 5 );gap>## NilpotentQuotient( F : class := 5 ); gap>H := NilpotentQuotient( F, 5 );

Pcp-group with orders [ 0, 0 ]
Pcp-group with orders [ 0, 0, 0 ]
Pcp-group with orders [ 0, 0, 0, 0, 0, 0 ]
Note that the lower central series in the example is part of the data returned by the standalone program. Therefore, the execution of the function LowerCentralSeries takes no time.
The next example computes the class-4 quotient of the infinite dihedral group. The group is soluble but not nilpotent. The first factor of its lower central series is a Klein four group and all the other factors are cyclic or order \(2\).
gap>F := FreeGroup( 2 );
<free group on the generators [ f1, f2 ]>
gap>G := F / [F.1^2, F.2^2];
<fp group on the generators [ f1, f2 ]>
gap>H := NilpotentQuotient( G, 4 );
Pcp-group with orders [ 2, 2, 2, 2, 2 ]

In the following example identical generators are used in order to express the fact that the group is nilpotent of class \(3\). A group is nilpotent of class \(3\) if it satisfies the identical relation \([x_1,x_2,x_3,x_4]=1\) (cf. Section 2.5). The result is the free nilpotent group of class \(3\) on two generators.
gap>F := FreeGroup( "a", "b", "w", "x", "y", "z" );
<free group on the generators [ a, b, w, x, y, z ]>
gap>G := F / [ LeftNormedComm( [F.3,F.4,F.5,F.6] ) ];
<fp group of size infinity on the generators [ a, b, w, x, y, z ]>
gap>## The following is equivalent to: gap>## NilpotentQuotient( G : idgens := [F.3,F.4,F.5,F.6] );gap>H := NilpotentQuotient( G, [F.3,F.4,F.5,F.6] );

Pcp-group with orders [ 0, 0 ], Pcp-group with orders [ ] ]
The following example uses expression trees in order to specify the third Engel law for the free group on \(3\) generators.
The example above also shows that the relative orders of an abelian polycyclic group need not be the abelian invariants (elementary divisors) of the group. Each zero corresponds to a generator of infinite order. The number of zeroes is always correct.
This function is a special version of NilpotentQuotient (3.1-1) which enforces the \(n\)-th Engel identity on the nilpotent quotients of the group specified by fp-group or by input-file. It accepts the same options as NilpotentQuotient.
The Engel condition can also be enforced by using identical generators and the Engel law and NilpotentQuotient (3.1-1). See the examples there.
The following example computes the relatively free fifth Engel group on two generators, determines its (normal) torsion subgroup and computes the corresponding quotient group. The quotient modulo the torsion subgroup is torsion-free. Therefore, there is a nilpotent presentation without power relations. The example computes a nilpotent presentation for the torsion free factor group through the upper central series. The factors of the upper central series in a torsion free group are torsion free. In this way one obtains a set of generators of infinite order and the resulting nilpotent presentation has no power relations.
This function computes an epimorphism from the group \(G\) given by the finite presentation fp-group onto \(G/\gamma_{c+1}(G).\) If c is not given, then the largest nilpotent quotient of \(G\) is computed and an epimorphism from \(G\) onto the largest nilpotent quotient of \(G\). If \(G\) does not have a largest nilpotent quotient, the function will not terminate if \(c\) is not given.
The optional argument id-gens is a list of generators of the free group underlying the finitely presented group fp-group. The generators in this list are treated as identical generators. Consequently, all relations of the fp-group involving these generators are treated as identical relations for these generators.
If identical generators are specified, then the epimorphism returned maps the group generated by the `non-identical' generators onto the nilpotent factor group. See the last example below.
The function understands the same options as the function NilpotentQuotient (3.1-1).
gap>F := FreeGroup(3);
<free group on the generators [ f1, f2, f3 ]>
gap>phi := NqEpimorphismNilpotentQuotient( F, 5 );
[ f1, f2, f3 ] -> [ g1, g2, g3 ]

<fp group on the generators [ a, b ]>

gap>F := FreeGroup( "a", "b", "u", "v", "x" );

gap>U := Source(phi);
Group([ a, b ])
gap>ImageElm( phi, LeftNormedComm( [U.1*U.2, U.2^-1,U.2^-1,U.2^-1,] ) );
id
Note that the last epimorphism is a map from the group generated by \(a\) and \(b\) onto the nilpotent quotient. The identical generators are used only to formulate the identical relator. They are not generators of the group \(G\). Also note that the left-normed commutator above is mapped to the identity as \(G\) satisfies the specified identical law.
3.1-4 LowerCentralFactors
‣ LowerCentralFactors( ... )
( function )
This function accepts the same arguments and options as NilpotentQuotient (3.1-1) and returns a list containing the abelian invariants of the central factors in the lower central series of the specified group.
The argument m must be a positive integer. The function returns a list with m expression tree symbols named x1, x2,... The optional parameter prefix must be a string and is used instead of x if present.
Alternatively, the function can be executed with a list of strings str1, str2, .... It returns a list of symbols with these strings as names.
The following operations are defined for expression trees: multiplication, inversion, exponentiation, forming commutators, forming conjugates.
gap>t := ExpressionTrees( 3 );
[ x1, x2, x3 ]
gap>tree := Comm( t[1], t[2] )^3/LeftNormedComm( [t[1],t[2],t[3],t[1]] );

3.2-2 EvaluateExpTree
‣ EvaluateExpTree( tree, symbols, values )
( function )
The argument tree is an expression tree followed by the list of those symbols symbols from which the expression tree is built up. The argument values is a list containing a constant for each symbol. The function substitutes each value for the corresponding symbol and computes the resulting value for tree.

3.3 Auxiliary Functions
3.3-1 NqReadOutput
‣ NqReadOutput( stream )
( function )
The only argument stream is an output stream of the ANU NQ. The function reads the stream and returns a record that has a component for each global variable used in the output of the ANU NQ, see NqGlobalVariables (3.4-3).
3.3-2 NqStringFpGroup
‣ NqStringFpGroup( fp-group[, idgens] )
( function )
The function takes a finitely presented group fp-group and returns a string in the input format of the ANU NQ. If the list idgens is present, then it must contain generators of the free group underlying the finitely presented group FreeGroupOfFpGroup (Reference: FreeGroupOfFpGroup). The generators in idgens are treated as identical generators.

Pcp-group with orders [ 7, 7, 7 ]
3.3-3 NqStringExpTrees
‣ NqStringExpTrees( fp-group[, idgens] )
( function )
The function takes a finitely presented group fp-group given in terms of expression trees and returns a string in the input format of the ANU NQ. If the list idgens is present, then it must contain a sublist of the generators of the presentation. The generators in idgens are treated as identical generators.
The function ElementaryDivisorsMat (Reference: ElementaryDivisorsMat) only returns the non-zero elementary divisors of an integer matrix. This function computes the elementary divisors of int-mat and adds the appropriate number of zeroes in order to make it easier to recognize the isomorphism type of the abelian group presented by the integer matrix. At the same time ones are stripped from the list of elementary divisors.
3.4 Global Variables
3.4-1 NqRuntime
‣ NqRuntime
( global variable )
This variable contains the number of milliseconds of runtime of the last call of ANU NQ.
This variable contains a list of strings which are the standard command line options passed to the ANU NQ in each call. Modifying this variable can be used to pass additional options to the ANU NQ.
gap>NqDefaultOptions;
[ "-g", "-p", "-C", "-s" ]
The option -g causes the ANU NQ to produce output in GAP-format. The option -p prevents the ANU NQ from listing the pc-presentation of the nilpotent quotient at the end of the calculation. The option -C invokes the combinatorial collector. The option -s is effective only in conjunction with options for computing with Engel identities and instructs the ANU NQ to use only semigroup words in the generators as instances of an Engel law.
3.4-3 NqGlobalVariables
‣ NqGlobalVariables
( global variable )
This variable contains a list of strings with the names of the global variables that are used in the output stream of the ANU NQ. While the output stream is read, these global variables are assigned new values. To avoid overwriting these variables in case they contain values, their contents is saved before reading the output stream and restored afterwards.
3.5 Diagnostic Output

An old problem in the context of Engel elements is the question: Is a right n-Engel element left n-Engel? It is known that the answer is no. For details about the history of the problem, see [NN94]. In this paper the authors show that for n>4 there are nilpotent groups with right n-Engel elements no power of which is a left n-Engel element. The insight was based on computations with the ANU NQ which we reproduce here. We also show the cases 5>n.

This shows that each right 2-Engel element in a finitely generated nilpotent group is a left 2-Engel element. Note that the group above is the largest nilpotent group generated by two elements, one of which is right 2-Engel. Every nilpotent group generated by an arbitrary element and a right 2-Engel element is a homomorphic image of the group H.

Introduction
This package provides an interface between &GAP; 4 and the
Australian National University Nilpotent Quotient Program (ANU NQ).
The ANU NQ was implemented as part of the author's work towards his
PhD at the Australian National University, hence the name of the
program. The program takes as input a finite presentation of a
group and successively computes factor groups modulo the terms of
the lower central series of the group. These factor groups are
computed in terms of polycyclic presentations.
The ANU NQ is implemented in the programming language C. The
implementation has been developed in a Unix environment and Unix is
currently the only operating system supported. It runs on a number
of different Unix versions, e.g. Solaris and Linux.
For integer matrix computations it relies on the GNU MP package and requires this package to be installed on
your system.
This package relies on the functionality for polycyclic groups
provided by the &GAP; package polycyclic and requires the package
polycyclic to be installed as a &GAP; package on
your computer system.
Comments, bug reports and suggestions are very welcome, please
submit them via our
https://github.com/gap-system/nq/issues.
This manual contains references to parts of the &GAP; Reference
Manual which are typeset in a slightly idiosyncratic way. The
following example shows how such references are printed: 'For
further information on creating a free group see .' The text in bold face refers to the &GAP;
Reference Manual.
Each item in the list of references at the end of this manual is
followed by a list of numbers that specify the pages of the manual
where the reference occurs.

The nq command line interfaceHow to use the ANU NQ
If you start the ANU NQ by typing
nq -X
you will get the following message:
unknown option: -X
usage: nq [-a] [-M] [-d] [-g] [-v] [-s] [-f] [-c] [-m]
[-t <n>] [-l <n>] [-r <n>] [-n <n>] [-e <n>]
[-y] [-o] [-p] [-E] [<presentation>] [<class>]
All parameters in square brackets are optional. The parameter
<presentation> has to be the name of a file that contains a finite
group presentation for which a nilpotent quotient is to be calculated.
This file name must not start with a digit. If it is not present, nq
will read the presentation from standard input. The parameter <class>
restricts the computation of the nilpotent quotient to at most that
(nilpotency) class, i.e. the program calculates the quotient group of
the (c+1)-th term of the lower central series. If <class> is omitted,
the program computes successively the factor groups of the lower
central series of the given group. If there is a largest nilpotent
quotient, i.e., if the lower central series becomes constant, the
program will eventually terminate with the largest nilpotent quotient.
If there is no largest nilpotent quotient, the program will run
forever (or more precisely will run out of resources). On termination
the program prints a nilpotent presentation for the nilpotent quotient
it has computed.
The options -l, -r and -e can be used to enforce Engel conditions on
the nilpotent quotient to be calculated. All these options have to be
followed by a positive integer <n>. Their meaning is the following:
-n <k>
This option forces the first k generators to be left
or right Engel element if also the option -l or -r
(or both) is present. Otherwise it is ignored.
-l <n>
This forces the first k generators g_1,...,g_k of the
nilpotent quotient Q to be left n-Engel elements, i.e.,
they satisfy [x,...,x,g_i] = 1 (x occurring n-times)
for all x in Q and 1 <= i <= k. If the option -n is not
used, then k = 1.
-r <n>
This forces the first k generators g_1,...,g_k of the
nilpotent quotient Q to be right n-Engel elements,i.e.,
they satisfy [g_i,x,..,x] = 1 (x occurring n-times)
for all x in Q and 1 <= i <= k. If the option -n is not
used, then k = 1.
-e <n>
This enforces the n-th Engel law on Q, i.e., [x,y,..,y]
= 1 (y occurring n-times) for all x,y in Q.
-t <n>
This option specifies how much CPU time the program is
allowed to use. It will terminate after <n> seconds of
CPU time. If <n> is followed (without space) by one of
the letters m, h or d, <n> specifies the time in
minutes, hours or days, respectively.
The other options have the following meaning. Care has to be taken
when the options -s or -c are used since the resulting nilpotent
quotient need NOT satisfy the required Engel condition. The reason
for this is that a smaller set of test words is used if one of these
two options are present. Although this smaller set of test words seems
to be sufficient to enforce the required Engel condition, this fact
has not been proven.
-a
For each factor of the lower central series a file is
created in the current directory that contains an integer
matrix describing the factor as abelian group. The first
number in that file is the number of columns of the matrix.
Then the matrix follows in row major order. The matrix for
the i-th factor is put into the file
<presentation>.abinv.<i>.
-p
toggles printing of the pc presentation for the nilpotent
quotient at the end of a calculation.
-s
This option causes the program to check only semigroup
words in the generating set of the nilpotent quotient when
an Engel condition is enforced. If none of the options -l,
-r or -e are present, it is ignored.
-f
This option causes to check semiwords in the generating set
of the nilpotent quotient first and then all other words
that need to be checked. It is ignored if the option -s is
used or none of the options -l, -r or -e are present.
-c
This option stops checking the Engel law at each class if
all the checks of a certain weight did not yield any
non-trivial instances of the law.
-d
Switch on debug mode and perform checks during the
computation. Not yet implemented.
-o
In checking Engel identities, instances are process in the
order of increased weight. This flag reverses the order.
-y
Enforce the identities x^8 and [ [x1,x2,x3], [x4,x5,x6] ]
on the nilpotent quotient.
-v
Switch on verbose mode.
-g
Produce GAP output. Presently the GAP output consists only
of a sequence of integer matrices whose rows are relations
of the factors of the lower central series as abelian
groups. This will change as soon as GAP can handle infinite
polycyclic groups.
-E
the *last* n generators are Engel generators. This works
in conjunction with option -n.
-m
output the relation matrix for each factor of the lower
central series. The matrices are written to files with the
names 'matrix.<cl>' where <cl> is replaced by the number of
the factor in the lower central series. Each file contains
first the number of columns of the matrix and then the rows
of the matrix. The matrix is written as each relation is
produced and is not in upper triangular form.
-M
output the relation matrix before and after relations have
been enforced. This results in two groups of files with
names '<pres>.nilp.<cl>' and '<pres>.mult.<cl>' where
<pres> is the name of the input files and <cl> is the
class. The matrices are in upper triangular form.
The input format for presentations
The input format for finite presentations resembles the way many
people write down a presentation on paper. Here are some examples of
presentations that the ANU NQ accepts:
# free group of rank 2
< a, b, c | [a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation
(a*[b,(a*c)])^6 # something that looks complicated
>
]]>
A presentation starts with '<' followed be a list of generators
separated by commas. Generator names are strings that contain only upper
and lower case letters, digits, dots and underscores and that do not
start with a digit. The list of generator names is separated from the
list of relators/relations by the symbol '|'. Relators and relations are
separated by commas and can be mixed arbitrarily. Parentheses can be
used in order to group subexpressions together. Square brackets can be
used in order to form left normed commutators. The symbols '*' and '^'
can be used to form products and powers, respectively. The presentation
finishes with the symbol '>'. A comment starts with the symbol '#'
and finishes at the end of the line. The file src/presentation.c
contains a complete grammar for the presentations accepted by the ANU NQ.
An example
Let G be the free group on two generators x and y. The input file
(called free2.fp here) contains the following:
]]>
Computing the class 3 quotient with the ANU NQ by typing
produces the following output:
A
# y |---> B
# The nilpotent quotient :
# Class : 3
# Nr of generators of each class : 2 1 2
# The definitions:
# C := [ B, A ]
# D := [ B, A, A ]
# E := [ B, A, B ]
# total runtime : 1 msec
# total size : 0 byte
## Total time spent on integer matrices: 0
]]>
Most of the comments are fairly self-explanatory. One note of caution is
necessary: The number of generators for each factor of the lower central
series is not the minimal number possible but is the number of
generators that the ANU NQ chose to use. This will be improved in one of
the future version of the program. The epimorphism from the original
group onto the nilpotent quotient is printed in a somewhat confusing
way. The generators on the left hand side of the arrows correspond to
the generators in the original presentation but are printed with
different names. This will be fixed in one of the next version.
Some remarks about the algorithm
The implementation of the algorithm is fairly straight forward. The
program uses a weighted nilpotent presentation with definitions to
represent a nilpotent group. Calculations in the nilpotent group are
done using a collector from the left without combinatorial collection.
Generators for the c-th lower central factor are defined as
commutators of the form [y,x], where x is a generator of
weight 1 and y is a generator of weight c-1. Then the
program calculates the necessary changes (tails) for all relations which
are not definitions, runs through the consistency check and evaluates
the original relations on the polycyclic presentation. This gives a list
of words, which have to be made trivial in order to obtain a consistent
polycyclic presentation representing a nilpotent quotient of the given
finitely presented group. This list is converted into a integer matrix,
which is transformed into upper triangular form using the Kannan-Bachem
algorithm. The GNU multiple precision package is used for this.

GAP (nq) - Chapter 2: General remarks
In this chapter we define notation used throughout this manual and recollect basic facts about nilpotent groups. We also provide some background information about the functionality implemented in this package.
2.1 Commutators and the Lower Central Series
The commutator of two elements \(h_1\) and \(h_2\) of a group \(G\) is the element \(h_1^{-1}h_2^{-1}h_1h_2\) and is denoted by \([h_1,h_2]\). It satisfies the equation \(h_1h_2 = h_2h_1[h_1,h_2]\) and can be interpreted as the correction term that has to be introduced into a word if two elements of a group are interchanged. Iterated commutators are written in left-normed fashion: \([h_1,h_2,\ldots,h_{n-1},h_n]=[[h_1,h_2,\ldots,h_{n-1}],h_n]\).
The lower central series of \(G\) is defined inductively as \(\gamma_1(G) = G, \gamma_i(G) = [\gamma_{i-1}(G),G]\) for \(i \ge 2\). Each term in the lower central series is a normal (even fully invariant) subgroup of \(G\). The factors of the lower central series are abelian groups. On each factor the induced action of \(G\) via conjugation is the trivial action.
The factor \(\gamma_k(G)/\gamma_{k+1}(G)\) is generated by the elements \([g,h]\gamma_{k+1}(G),\) where \(g\) runs through a set of (representatives of) generators for \(G/\gamma_2(G)\) and \(h\) runs through a set of (representatives of) generators for \(\gamma_{k-1}(G)/\gamma_k(G).\) Therefore, each factor of the lower central series is finitely generated if \(G\) is finitely generated.
If one factor of the lower central series is finite, then all subsequent factors are finite. Then the exponent of the \(k+1\)-th factor is a divisor of the exponent of the \(k\)-th factor of the lower central series. In particular, the exponents of all factors of the lower central series are bounded by the exponent of the first finite factor of the lower central series.
2.2 Nilpotent groups
A group \(G\) is called nilpotent if there is a positive integer \(c\) such that all \((c+1)\)-fold commutators are trivial in \(G.\) The smallest integer with this property is called the nilpotency class of \(G\). In terms of the lower central series a group \(G \not= 1\) has nilpotency class \(c\) if and only if \(\gamma_{c}(G) \not= 1\) and \(\gamma_{c+1}(G) = 1\).
Examples of nilpotent groups are finite \(p\)-groups, the group of unitriangular matrices over a ring with one and the factor groups of a free group modulo the terms of its lower central series.
Finiteness of a nilpotent group can be decided by the group's commutator factor group. A nilpotent group is finite if and only if its commutator factor group is finite. A group whose commutator factor group is finite can only have finite nilpotent quotient groups.
By refining the lower central series of a finitely generated nilpotent group one can obtain a (sub)normal series \(G_1>G_2>...>G_{k+1}=1\) with cyclic (central) factors. Therefore, every finitely generated nilpotent group is polycyclic. Such a polycyclic series gives rise to a polycyclic generating sequence by choosing a generator \(a_i\) for each cyclic factor \(G_i/G_{i+1}\). Let \(I\) be the set of indices such that \(G_i/G_{i+1}\) is finite. A simple induction argument shows that every element of the group can be written uniquely as a normal word\(a_1^{e_1}\ldots a_n^{e_n}\) with integers \(e_i\) and \(0\leq e_i<m_i\) for \(i\in I\).
2.3 Nilpotent presentations
From a polycyclic generating sequence one can obtain a polycyclic presentation for the group. The following set of power and commutator relations is a defining set of relations. The power relations express \(a_i^{m_i}\) in terms of the generators \(a_{i+1},\ldots,a_n\) whenever \(G_i/G_{i+1}\) is finite with order \(m_i\). The commutator relations are obtained by expressing \([a_j,a_i]\) for \(j>i\) as a word in the generators \(a_{i+1},\ldots,a_n\). If the polycyclic series is obtained from refining the lower central series, then \([a_j,a_i]\) is even a word in \(a_{j+1},\ldots,a_n\). In this case we obtain a nilpotent presentation.
To be more precise, a nilpotent presentation is given on a finite number of generators \(a_1,\ldots,a_n\). Let \(I\) be the set of indices such that \(G_i/G_{i+1}\) is finite. Let \(m_i\) be the order of \(G_i/G_{i+1}\) for \(i\in I\). Then a nilpotent presentation has the form
\[
\langle a,\ldots,a_n |
a_i^{m_i} = w_{ii}(a_{i+1},\ldots,a_n)
\mbox{ for } i\in I;\;
[a_j,a_i] = w_{ij}(a_{j+1},\ldots,a_n)
\mbox{ for } 1\leq i < j\leq n\rangle
\]
Here, \(w_{ij}(a_k,\ldots,a_n)\) denotes a group word in the generators \(a_k,\ldots,a_n\).
In a group given by a polycyclic presentation each element in the group can be written as a normal word\(a_1^{e_1}\ldots a_n^{e_n}\) with \(e_i \in \mathbb{Z}\) and \(0 \leq e_i < m_i\) for \(i \in I\). A procedure called collection can be used to convert an arbitrary word in the generators into an equivalent normal word. In general, the resulting normal word need not be unique. The result of collecting a word may depend on the steps chosen during the collection procedure. A polycyclic presentation with the property that two different normal words are never equivalent is called consistent. A polycyclic presentation derived from a polycyclic series as above is consistent. The following example shows an inconsistent polycyclic presentation
\[\langle a,b\mid a^2, b^a = b^2 \rangle \]
as \(b = baa = ab^2a = a^2b^4 = b^4\) which implies \(b^3=1\). Here we have the equivalent normal words \(b^3\) and the empty word. It can be proved that consistency can be checked by collecting a finite number of words in the given generating set in two essentially different ways and checking if the resulting normal forms are the same in both cases. See Chapter 9 of the book [Sim94] for an introduction to polycyclic groups and polycyclic presentations.
For computations in a polycyclic group one chooses a consistent polycyclic presentation as it offers a simple solution to the word problem: Equality between two words is decided by collecting both words to their respective normal forms and comparing the normal forms. Nilpotent groups and nilpotent presentations are special cases of polycyclic groups and polycyclic presentations. Nilpotent presentations allow specially efficient collection methods. The package Polycyclic provides algorithms to compute with polycyclic groups given by a polycyclic presentation.
However, inconsistent nilpotent presentations arise naturally in the nilpotent quotient algorithm. There is an algorithm based on the test words for consistency mentioned above to modify the arising inconsistent presentations suitably to obtain a consistent one for the same group.
2.4 A sketch of the algorithm
The input for the ANU NQ in its simplest form is a finite presentation \(\langle X|R\rangle\) for a group \(G\). The first step of the algorithm determines a nilpotent presentation for the commutator quotient of \(G\). This is a presentation of the class-\(1\) quotient of \(G\). Call its generators \(a_1,...,a_d\). It also determines a homomorphism of \(G\) onto the commutator quotient and describes it by specifying the image of each generator in \(X\) as a word in the \(a_i\).
For the general step assume that the algorithm has computed a nilpotent presentation for the class-\(c\) quotient of \(G\) and that \(a_1,...,a_d\) are the generators introduced in the first step of the algorithm. Furthermore, there is a map from X into the class-\(c\) quotient describing the epimorphism from \(G\) onto \(G/\gamma_{c+1}(G)\).
Let \(b_1,...b_k\) be the generators from the last step of the algorithm, the computation of \(\gamma_c(G)/\gamma_{c+1}(G)\). This means that \(b_1,...b_k\) generate \(\gamma_c(G)/\gamma_{c+1}(G)\). Then the commutators \([b_j,a_i]\) generate \(\gamma_{c+1}(G)/\gamma_{c+2}(G)\). The algorithm introduces new, central generators \(c_{ij}\) into the presentation, adds the relations \([b_j,a_i] = c_{ij}\) and modifies the existing relations by appending suitable words in the \(c_{ij}\), called tails, to the right hand sides of the power and commutator relations. The resulting presentation is a nilpotent presentation for the nilpotent cover of \(G/\gamma_{c+1}(G)\). The nilpotent cover is the largest central extension of \(G/\gamma_{c+1}(G)\) generated by \(d\) elements. It is is uniquely determined up to isomorphism.
The resulting presentation of the nilpotent cover is in general inconsistent. Consistency is achieved by running the consistency test. This results in relations among the generators \(c_{ij}\) which can be used to eliminate some of those generators or introduce power relations. After this has been done we have a consistent nilpotent presentation for the nilpotent cover of \(G/\gamma_{c+1}(G)\).
Furthermore, the nilpotent cover need not satisfy the relations of \(G\). In other words, the epimorphism from \(G\) onto \(G/\gamma_{c+1}(G)\) cannot be lifted to an epimorphism onto the nilpotent cover. Applying the epimorphism to each relator of \(G\) and collecting the resulting words of the nilpotent cover yields a set of words in the \(c_{ij}\). This gives further relations between the \(c_{ij}\) which leads to further eliminations or modifications of the power relations for the \(c_{ij}\).
After this, the inductive step of the ANU NQ is complete and a consistent nilpotent presentation for \(G/\gamma_{c+2}(G)\) is obtained together with an epimorphism from \(G\) onto the class-\((c+1)\) quotient.
Chapter 11 of the book [Sim94] discusses a nilpotent quotient algorithm. A description of the implementation in the ANU NQ is contained in [Nic96]
2.5 Identical Relations
Let \(w\) be a word in free generators \(x_1,\ldots,x_n\). A group \(G\) satisfies the relation \(w=1\)identically if each map from \(x_1,\ldots,x_n\) into \(G\) maps \(w\) to the identity element of \(G\). We also say that \(G\) satisfies the identical relation\(w=1\) or satisfies the law\(w=1\). In slight abuse of notation, we call the elements \(x_1,\ldots,x_n\)identical generators.
Common examples of identical relations are: A group of nilpotency class at most \(c\) satisfies the law \([x_1,\ldots,x_{c+1}]=1\). A group that satisfies the law \([x,y,\ldots,y]=1\) where \(y\) occurs \(n\)-times, is called an \(n\)-Engel group. A group that satisfies the law \(x^d=1\) is a group of exponent \(d\).
To describe finitely presented groups that satisfy one or more laws, we extend a common notation for finitely presented groups by specifying the identical generators as part of the generator list, separated from the group generators by a semicolon: For example
\[
\langle a,b,c; x,y | x^5, [x,y,y,y]\rangle
\]
is a group on 3 generators \(a,b,c\) of exponent \(5\) satisfying the 3rd Engel law. The presentation above is equivalent to a presentation on 3 generators with an infinite set of relators, where the set of relators consists of all fifth powers of words in the generators and all commutators \([x,y,y,y]\) where \(x\) and \(y\) run through all words in the generators \(a,b,c\). The standalone programme accepts the notation introduced above as a description of its input. In GAP 4 finitely presented groups are specified in a different way, see NilpotentQuotient (3.1-1) for a description.
This notation can also be used in words that mix group and identical generators as in the following example:
\[
\langle a,b,c; x | [x,c], [a,x,x,x] \rangle
\]
The first relator specifies a law which says that \(c\) commutes with all elements of the group. The second turns \(a\) into a third right Engel element.
An element \(a\) is called a right \(n\)-th Engel element or a right \(n\)-Engel element if it satisfies the commutator law \([a,x,...,x]=1\) where the identical generator \(x\) occurs \(n\)-times. Likewise, an element \(b\) is called an left \(n\)-th Engel element or left \(n\)-Engel element if it satisfies the commutator law \([x,b,b,...b]=1\).
Let \(G\) be a nilpotent group. Then \(G\) satisfies a given law if the law is satisfied by a certain finite set of instances given by Higman's Lemma, see [Hig59]. The ANU NQ uses Higman's Lemma to obtain a finite presentation for groups that satisfy one or several identical relations.
2.6 Expression Trees
Expressions involving commutators play an important role in the context of nilpotent groups. Expanding an iterated commutator produces a complicated and long expression. For example,
Evaluating a commutator \([a,b]\) is done efficiently by computing the equation \((ba)^{-1}ab\). Therefore, for each commutator we need to perform two multiplications and one inversion. Evaluating \([x,y,z]\) needs four multiplications and two inversions. Evaluation of an iterated commutator with \(n\) components takes \(2n-1\) multiplications and \(n-1\) inversions. The expression on the right hand side above needs \(9\) multiplications and \(5\) inversions which is clearly much more expensive than evaluating the commutator directly.
Assuming that no cancellations occur, expanding an iterated commutator with n components produces a word with \(2^{n+1}-2^{n-1}-2\) factors half of which are inverses. A similar effect occurs whenever a compact expression is expanded into a word in generators and inverses, for example \((ab)^{49}\).
Therefore, it is important not to expand expressions into a word in generators and inverses. For this purpose we provide a mechanism which we call here expression trees. An expression tree preserves the structure of a given expression. It is a (binary) tree in which each node is assigned an operation and whose leaves are generators of a free group or integers. For example, the expression \([(xy)^2, z]\) is stored as a tree whose top node is a commutator node. The right subtree is just a generator node (corresponding to \(z\)). The left subtree is a power node whose subtrees are a product node on the left and an integer node on the right. An expression tree can involve products, powers, conjugates and commutators. However, the list of available operations can be extended.
Evaluation of an expression tree is done recursively and requires as many operations as there are nodes in the tree. An expression tree can be evaluated in a specific group by the function EvaluateExpTree (3.2-2).
A presentation specified by expression trees is a record with the components .generators and .relations. See section 3.2 for a description of the functions that produce and manipulate expression trees.
The ANU NQ is written in C, but not in ANSI C. I hope to make one of the next versions ANSI compliable. However, it uses a fairly restricted subset of the language so that it should be easy to compile it in new environments. The code is 64-bit clean. If you have difficulties with porting it to a new environment, let me know and I'll be happy to assist if time permits.
The program has two collectors: a simple collector from the left as described in [LGS90] and a combinatorial from the left collector as described in [VL90]. The combinatorial collector is always faster than the simple collector, therefore, it is the collector used by this package by default. This can be changed by modifying the global variable NqDefaultOptions (3.4-2).
In a polycyclic group with generators that do not have power relations, exponents may become arbitrarily large. Experience shows that this happens rarely in the computations done by the ANU NQ. Exponents are represented by 32-bit integers. The collectors perform an overflow check and abort the computation if an overflow occurred. In a GNU environment the program can be compiled using the `long long' 64-bit integer type. For this uncomment the relevant line in src/Makefile and recompile the program.
As part of the step that enforces consistency and the relations of the group, the ANU NQ performs computations with integer matrices and converts them to Hermite Normal Form. The algorithm used here is a variation of the Kanan-Bachem algorithm based on the GNU multiple precision package GNU MP [GMP]. Experience shows that the integer matrices are usually fairly sparse and Kanan-Bachem seems to be sufficient in this context. However, the implementation might benefit from a more efficient strategy for computing Hermite Normal Forms. This is a topic for further investigations.
As the program does not compute the Smith Normal Form for each factor of the lower central series but the Hermite Normal Form, it does not necessarily obtain a minimal generating set for each factor of the lower central series. The following is a simple example of this behaviour. We take the presentation
\[
\langle x, y | x^2 = y \rangle
\]
The group is clearly isomorphic to the additive group of the integers. Applying the ANU NQ to this presentation gives the following nilpotent presentation:
\[
\langle A,B | A^2 = B, [B,A] \rangle
\]
A nilpotent presentation on a minimal generating set would be the presentation of the free group on one generator:
\[
\langle A | \; \rangle
\]
2.8 The input format of the standalone
The input format for finite presentations resembles the way many people write down a presentation on paper. Here are some examples of presentations that the ANU NQ accepts:
< a, b | > # free group of rank 2
< a, b, c; x, y |
[a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation
(a*[b,(a*c)])^6, # something that looks complicated
[x,y,y,y,y], # an identical relation
[c,x,x,x,x,x] # c is a fifth right Engel element
>
A presentation starts with '<' followed by a list of generators separated by commas. Generator names are strings that contain only upper and lower case letters, digits, dots and underscores and that do not start with a digit. The list of generator names is separated from the list of relators/relations by the symbol '\(\mid\)'. The list of generators can be followed by a list of identical generators separated by a semicolon. Relators and relations are separated by commas and can be mixed arbitrarily. Parentheses can be used in order to group subexpressions together. Square brackets can be used in order to form left normed commutators. The symbols '*' and '^' can be used to form products and powers, respectively. The presentation finishes with the symbol '>'. A comment starts with the symbol '#' and finishes at the end of the line. The file src/presentation.c contains a complete grammar for the presentations accepted by the ANU NQ.
Typically, the input for the standalone is put into a file by using a standard text editor. The file can be passed as an argument to the function NilpotentQuotient (3.1-1). It is also possible to put a presentation in the standalone's input format into a string and use the string as argument for NilpotentQuotient (3.1-1).
If you installed the package in another "pkg" directory than the standard "pkg" directory in your GAP 4 installation, then you have to do two things. Firstly during compilation you have to use the option --with-gaproot=PATH of the configure script where "PATH" is a path to the main GAP root directory (if not given the default "../.." is assumed). That is, run
./configure --with-gaproot=PATH
Secondly you have to specify the path to the directory containing your "pkg" directory to GAP's list of directories. This can be done by starting GAP with the "-l" command line option followed by the name of the directory and a semicolon. Then your directory is prepended to the list of directories searched. Otherwise the package is not found by GAP. Of course, you can add this option to your GAP startup script.
Another issue that can occur when running configure is that it may fail to locate the the GNU multiple precision library (GMP [GMP]) which ANU NQ requires to work. This library is also used by GAP and hence normally should be available on your system anyway. But if this is not the case for some reason, it has to be installed first. A copy of GMP can be obtained from http://gmplib.org/.
In order for the configure script to find your copy of GMP, you may have tell it where to find it via --with-gmp=PATH, where "PATH" is the path where GMP was installed:
./configure --with-gmp=PATH
Yf necessary, you may combine --with-gmp and --with-gaproot.
5.2 Compiling the nq binary
If configure reports no problems, the next step is to start the compilation:
make
A compiled version of the program named nq is then placed into the directory bin/<complicated name>. The <complicated name> component encodes the operating system and the compiler used. This allows you to compile NQ on several architectures sharing the same files system.
If there are any warnings or even fatal error messages during the compilation process, please submit a bug report about that following the instructions in Section 5.4
5.3 Testing
After the compilation is finished you can check if the ANU NQ is running properly on your system. Simply type
make test
This runs some computations and compares their output with the output files in the directory examples. If any errors are reported, please follow the instructions below.
5.4 Feedback
If you encounter problems with any of the above steps, please do not hesitate to contact us about this. You can either use the nq issue tracker or contact the GAP support group via support@gap-system.org. Please make sure to include information about the specific issue you encountered (e.g. steps to reproduce it, the specific error message), your operating system, the compiler you used and also the versions of GAP and this package that were involved.

ExamplesRight Engel elements
An old problem in the context of Engel elements is the question: Is
a right n-Engel element left n-Engel? It is known
that the answer is no. For details about the history of the
problem, see . In this paper the
authors show that for n>4 there are nilpotent groups with
right n-Engel elements no power of which is a left
n-Engel element. The insight was based on computations with
the ANU NQ which we reproduce here. We also show the cases

This shows that each right 2-Engel element in a finitely generated
nilpotent group is a left 2-Engel element. Note that the group above
is the largest nilpotent group generated by two elements, one of which
is right 2-Engel. Every nilpotent group generated by an arbitrary
element and a right 2-Engel element is a homomorphic image of the
group H.

Finally, we see that in a torsion-free group a right 5-Engel element
need not be a left 5-Engel element.

GAP (nq) - Appendix A: The nq command line interface
All parameters in square brackets are optional. The parameter <presentation> has to be the name of a file that contains a finite group presentation for which a nilpotent quotient is to be calculated. This file name must not start with a digit. If it is not present, nq will read the presentation from standard input. The parameter <class> restricts the computation of the nilpotent quotient to at most that (nilpotency) class, i.e. the program calculates the quotient group of the (c+1)-th term of the lower central series. If <class> is omitted, the program computes successively the factor groups of the lower central series of the given group. If there is a largest nilpotent quotient, i.e., if the lower central series becomes constant, the program will eventually terminate with the largest nilpotent quotient. If there is no largest nilpotent quotient, the program will run forever (or more precisely will run out of resources). On termination the program prints a nilpotent presentation for the nilpotent quotient it has computed. The options -l, -r and -e can be used to enforce Engel conditions on the nilpotent quotient to be calculated. All these options have to be followed by a positive integer <n>. Their meaning is the following:
-n <k>
This option forces the first k generators to be left or right Engel element if also the option -l or -r (or both) is present. Otherwise it is ignored.
-l <n>
This forces the first k generators g_1,...,g_k of the nilpotent quotient Q to be left n-Engel elements, i.e., they satisfy [x,...,x,g_i] = 1 (x occurring n-times) for all x in Q and 1 <= i <= k. If the option -n is not used, then k = 1.
-r <n>
This forces the first k generators g_1,...,g_k of the nilpotent quotient Q to be right n-Engel elements,i.e., they satisfy [g_i,x,..,x] = 1 (x occurring n-times) for all x in Q and 1 <= i <= k. If the option -n is not used, then k = 1.
-e <n>
This enforces the n-th Engel law on Q, i.e., [x,y,..,y] = 1 (y occurring n-times) for all x,y in Q.
-t <n>
This option specifies how much CPU time the program is allowed to use. It will terminate after <n> seconds of CPU time. If <n> is followed (without space) by one of the letters m, h or d, <n> specifies the time in minutes, hours or days, respectively.
The other options have the following meaning. Care has to be taken when the options -s or -c are used since the resulting nilpotent quotient need NOT satisfy the required Engel condition. The reason for this is that a smaller set of test words is used if one of these two options are present. Although this smaller set of test words seems to be sufficient to enforce the required Engel condition, this fact has not been proven.
-a
For each factor of the lower central series a file is created in the current directory that contains an integer matrix describing the factor as abelian group. The first number in that file is the number of columns of the matrix. Then the matrix follows in row major order. The matrix for the i-th factor is put into the file <presentation>.abinv.<i>.
-p
toggles printing of the pc presentation for the nilpotent quotient at the end of a calculation.
-s
This option causes the program to check only semigroup words in the generating set of the nilpotent quotient when an Engel condition is enforced. If none of the options -l, -r or -e are present, it is ignored.
-f
This option causes to check semiwords in the generating set of the nilpotent quotient first and then all other words that need to be checked. It is ignored if the option -s is used or none of the options -l, -r or -e are present.
-c
This option stops checking the Engel law at each class if all the checks of a certain weight did not yield any non-trivial instances of the law.
-d
Switch on debug mode and perform checks during the computation. Not yet implemented.
-o
In checking Engel identities, instances are process in the order of increased weight. This flag reverses the order.
-y
Enforce the identities x^8 and [ [x1,x2,x3], [x4,x5,x6] ] on the nilpotent quotient.
-v
Switch on verbose mode.
-g
Produce GAP output. Presently the GAP output consists only of a sequence of integer matrices whose rows are relations of the factors of the lower central series as abelian groups. This will change as soon as GAP can handle infinite polycyclic groups.
-E
the *last* n generators are Engel generators. This works in conjunction with option -n.
-m
output the relation matrix for each factor of the lower central series. The matrices are written to files with the names 'matrix.<cl>' where <cl> is replaced by the number of the factor in the lower central series. Each file contains first the number of columns of the matrix and then the rows of the matrix. The matrix is written as each relation is produced and is not in upper triangular form.
-M
output the relation matrix before and after relations have been enforced. This results in two groups of files with names '<pres>.nilp.<cl>' and '<pres>.mult.<cl>' where <pres> is the name of the input files and <cl> is the class. The matrices are in upper triangular form.
A.2 The input format for presentations
The input format for finite presentations resembles the way many people write down a presentation on paper. Here are some examples of presentations that the ANU NQ accepts:
< a, b | > # free group of rank 2
< a, b, c | [a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation
(a*[b,(a*c)])^6 # something that looks complicated
>
A presentation starts with '<' followed be a list of generators separated by commas. Generator names are strings that contain only upper and lower case letters, digits, dots and underscores and that do not start with a digit. The list of generator names is separated from the list of relators/relations by the symbol '|'. Relators and relations are separated by commas and can be mixed arbitrarily. Parentheses can be used in order to group subexpressions together. Square brackets can be used in order to form left normed commutators. The symbols '*' and '^' can be used to form products and powers, respectively. The presentation finishes with the symbol '>'. A comment starts with the symbol '#' and finishes at the end of the line. The file src/presentation.c contains a complete grammar for the presentations accepted by the ANU NQ.
A.3 An example
Let G be the free group on two generators x and y. The input file (called free2.fp here) contains the following:
< x, y | >
Computing the class 3 quotient with the ANU NQ by typing
nq free2.fp 3
produces the following output:

Most of the comments are fairly self-explanatory. One note of caution is necessary: The number of generators for each factor of the lower central series is not the minimal number possible but is the number of generators that the ANU NQ chose to use. This will be improved in one of the future version of the program. The epimorphism from the original group onto the nilpotent quotient is printed in a somewhat confusing way. The generators on the left hand side of the arrows correspond to the generators in the original presentation but are printed with different names. This will be fixed in one of the next version.
A.4 Some remarks about the algorithm
The implementation of the algorithm is fairly straight forward. The program uses a weighted nilpotent presentation with definitions to represent a nilpotent group. Calculations in the nilpotent group are done using a collector from the left without combinatorial collection. Generators for the c-th lower central factor are defined as commutators of the form [y,x], where x is a generator of weight 1 and y is a generator of weight c-1. Then the program calculates the necessary changes (tails) for all relations which are not definitions, runs through the consistency check and evaluates the original relations on the polycyclic presentation. This gives a list of words, which have to be made trivial in order to obtain a consistent polycyclic presentation representing a nilpotent quotient of the given finitely presented group. This list is converted into a integer matrix, which is transformed into upper triangular form using the Kannan-Bachem algorithm. The GNU multiple precision package is used for this.

[1X2 [33X[0;0YGeneral remarks[133X[101X
[33X[0;0YIn this chapter we define notation used throughout this manual and recollect
basic facts about nilpotent groups. We also provide some background
information about the functionality implemented in this package.[133X
[1X2.1 [33X[0;0YCommutators and the Lower Central Series[133X[101X
[33X[0;0YThe [13Xcommutator[113X of two elements [22Xh_1[122X and [22Xh_2[122X of a group [22XG[122X is the element
[22Xh_1^-1h_2^-1h_1h_2[122X and is denoted by [22X[h_1,h_2][122X. It satisfies the equation
[22Xh_1h_2 = h_2h_1[h_1,h_2][122X and can be interpreted as the correction term that
has to be introduced into a word if two elements of a group are
interchanged. Iterated commutators are written in [13Xleft-normed fashion[113X:
[22X[h_1,h_2,...,h_n-1,h_n]=[[h_1,h_2,...,h_n-1],h_n][122X.[133X
[33X[0;0YThe [13Xlower central series[113X of [22XG[122X is defined inductively as [22Xγ_1(G) = G, γ_i(G) =
[γ_i-1(G),G][122X for [22Xi ge 2[122X. Each term in the lower central series is a normal
(even fully invariant) subgroup of [22XG[122X. The factors of the lower central
series are abelian groups. On each factor the induced action of [22XG[122X via
conjugation is the trivial action.[133X
[33X[0;0YThe factor [22Xγ_k(G)/γ_k+1(G)[122X is generated by the elements [22X[g,h]γ_k+1(G),[122X where
[22Xg[122X runs through a set of (representatives of) generators for [22XG/γ_2(G)[122X and [22Xh[122X
runs through a set of (representatives of) generators for [22Xγ_k-1(G)/γ_k(G).[122X
Therefore, each factor of the lower central series is finitely generated if
[22XG[122X is finitely generated.[133X
[33X[0;0YIf one factor of the lower central series is finite, then all subsequent
factors are finite. Then the exponent of the [22Xk+1[122X-th factor is a divisor of
the exponent of the [22Xk[122X-th factor of the lower central series. In particular,
the exponents of all factors of the lower central series are bounded by the
exponent of the first finite factor of the lower central series.[133X
[1X2.2 [33X[0;0YNilpotent groups[133X[101X
[33X[0;0YA group [22XG[122X is called [13Xnilpotent[113X if there is a positive integer [22Xc[122X such that all
[22X(c+1)[122X-fold commutators are trivial in [22XG.[122X The smallest integer with this
property is called the [13Xnilpotency class[113X of [22XG[122X. In terms of the lower central
series a group [22XG not= 1[122X has nilpotency class [22Xc[122X if and only if [22Xγ_c(G) not= 1[122X
and [22Xγ_c+1(G) = 1[122X.[133X
[33X[0;0YExamples of nilpotent groups are finite [22Xp[122X-groups, the group of unitriangular
matrices over a ring with one and the factor groups of a free group modulo
the terms of its lower central series.[133X
[33X[0;0YFiniteness of a nilpotent group can be decided by the group's commutator
factor group. A nilpotent group is finite if and only if its commutator
factor group is finite. A group whose commutator factor group is finite can
only have finite nilpotent quotient groups.[133X
[33X[0;0YBy refining the lower central series of a finitely generated nilpotent group
one can obtain a (sub)normal series [22XG_1>G_2>...>G_k+1=1[122X with cyclic
(central) factors. Therefore, every finitely generated nilpotent group is
[13Xpolycyclic[113X. Such a [13Xpolycyclic series[113X gives rise to a polycyclic generating
sequence by choosing a generator [22Xa_i[122X for each cyclic factor [22XG_i/G_i+1[122X. Let [22XI[122X
be the set of indices such that [22XG_i/G_i+1[122X is finite. A simple induction
argument shows that every element of the group can be written uniquely as a
[13Xnormal word[113X [22Xa_1^e_1... a_n^e_n[122X with integers [22Xe_i[122X and [22X0≤ e_ii[122X as a word in the generators [22Xa_i+1,...,a_n[122X. If the
polycyclic series is obtained from refining the lower central series, then
[22X[a_j,a_i][122X is even a word in [22Xa_j+1,...,a_n[122X. In this case we obtain a
nilpotent presentation.[133X
[33X[0;0YTo be more precise, a [13Xnilpotent presentation[113X is given on a finite number of
generators [22Xa_1,...,a_n[122X. Let [22XI[122X be the set of indices such that [22XG_i/G_i+1[122X is
finite. Let [22Xm_i[122X be the order of [22XG_i/G_i+1[122X for [22Xi∈ I[122X. Then a nilpotent
presentation has the form[133X
[24X[33X[0;6Y\langle a,\ldots,a_n | a_i^{m_i} = w_{ii}(a_{i+1},\ldots,a_n) \mbox{ for }
i\in I;\; [a_j,a_i] = w_{ij}(a_{j+1},\ldots,a_n) \mbox{ for } 1\leq i <
j\leq n\rangle[133X
[124X
[33X[0;0YHere, [22Xw_ij(a_k,...,a_n)[122X denotes a group word in the generators [22Xa_k,...,a_n[122X.[133X
[33X[0;0YIn a group given by a polycyclic presentation each element in the group can
be written as a [13Xnormal word[113X [22Xa_1^e_1... a_n^e_n[122X with [22Xe_i ∈ Z[122X and [22X0 ≤ e_i <
m_i[122X for [22Xi ∈ I[122X. A procedure called [13Xcollection[113X can be used to convert an
arbitrary word in the generators into an equivalent normal word. In general,
the resulting normal word need not be unique. The result of collecting a
word may depend on the steps chosen during the collection procedure. A
polycyclic presentation with the property that two different normal words
are never equivalent is called [13Xconsistent[113X. A polycyclic presentation derived
from a polycyclic series as above is consistent. The following example shows
an inconsistent polycyclic presentation[133X
[24X[33X[0;6Y\langle a,b\mid a^2, b^a = b^2 \rangle[133X
[124X
[33X[0;0Yas [22Xb = baa = ab^2a = a^2b^4 = b^4[122X which implies [22Xb^3=1[122X. Here we have the
equivalent normal words [22Xb^3[122X and the empty word. It can be proved that
consistency can be checked by collecting a finite number of words in the
given generating set in two essentially different ways and checking if the
resulting normal forms are the same in both cases. See Chapter 9 of the book
[Sim94] for an introduction to polycyclic groups and polycyclic
presentations.[133X
[33X[0;0YFor computations in a polycyclic group one chooses a consistent polycyclic
presentation as it offers a simple solution to the word problem: Equality
between two words is decided by collecting both words to their respective
normal forms and comparing the normal forms. Nilpotent groups and nilpotent
presentations are special cases of polycyclic groups and polycyclic
presentations. Nilpotent presentations allow specially efficient collection
methods. The package [5XPolycyclic[105X provides algorithms to compute with
polycyclic groups given by a polycyclic presentation.[133X
[33X[0;0YHowever, inconsistent nilpotent presentations arise naturally in the
nilpotent quotient algorithm. There is an algorithm based on the test words
for consistency mentioned above to modify the arising inconsistent
presentations suitably to obtain a consistent one for the same group.[133X
[1X2.4 [33X[0;0YA sketch of the algorithm[133X[101X
[33X[0;0YThe input for the ANU NQ in its simplest form is a finite presentation [22X⟨
X|R⟩[122X for a group [22XG[122X. The first step of the algorithm determines a nilpotent
presentation for the commutator quotient of [22XG[122X. This is a presentation of the
class-[22X1[122X quotient of [22XG[122X. Call its generators [22Xa_1,...,a_d[122X. It also determines a
homomorphism of [22XG[122X onto the commutator quotient and describes it by
specifying the image of each generator in [22XX[122X as a word in the [22Xa_i[122X.[133X
[33X[0;0YFor the general step assume that the algorithm has computed a nilpotent
presentation for the class-[22Xc[122X quotient of [22XG[122X and that [22Xa_1,...,a_d[122X are the
generators introduced in the first step of the algorithm. Furthermore, there
is a map from X into the class-[22Xc[122X quotient describing the epimorphism from [22XG[122X
onto [22XG/γ_c+1(G)[122X.[133X
[33X[0;0YLet [22Xb_1,...b_k[122X be the generators from the last step of the algorithm, the
computation of [22Xγ_c(G)/γ_c+1(G)[122X. This means that [22Xb_1,...b_k[122X generate
[22Xγ_c(G)/γ_c+1(G)[122X. Then the commutators [22X[b_j,a_i][122X generate [22Xγ_c+1(G)/γ_c+2(G)[122X.
The algorithm introduces new, central generators [22Xc_ij[122X into the presentation,
adds the relations [22X[b_j,a_i] = c_ij[122X and modifies the existing relations by
appending suitable words in the [22Xc_ij[122X, called [13Xtails[113X, to the right hand sides
of the power and commutator relations. The resulting presentation is a
nilpotent presentation for the [13Xnilpotent cover[113X of [22XG/γ_c+1(G)[122X. The nilpotent
cover is the largest central extension of [22XG/γ_c+1(G)[122X generated by [22Xd[122X
elements. It is is uniquely determined up to isomorphism.[133X
[33X[0;0YThe resulting presentation of the nilpotent cover is in general
inconsistent. Consistency is achieved by running the consistency test. This
results in relations among the generators [22Xc_ij[122X which can be used to
eliminate some of those generators or introduce power relations. After this
has been done we have a consistent nilpotent presentation for the nilpotent
cover of [22XG/γ_c+1(G)[122X.[133X
[33X[0;0YFurthermore, the nilpotent cover need not satisfy the relations of [22XG[122X. In
other words, the epimorphism from [22XG[122X onto [22XG/γ_c+1(G)[122X cannot be lifted to an
epimorphism onto the nilpotent cover. Applying the epimorphism to each
relator of [22XG[122X and collecting the resulting words of the nilpotent cover
yields a set of words in the [22Xc_ij[122X. This gives further relations between the
[22Xc_ij[122X which leads to further eliminations or modifications of the power
relations for the [22Xc_ij[122X.[133X
[33X[0;0YAfter this, the inductive step of the ANU NQ is complete and a consistent
nilpotent presentation for [22XG/γ_c+2(G)[122X is obtained together with an
epimorphism from [22XG[122X onto the class-[22X(c+1)[122X quotient.[133X
[33X[0;0YChapter 11 of the book [Sim94] discusses a nilpotent quotient algorithm. A
description of the implementation in the ANU NQ is contained in [Nic96][133X
[1X2.5 [33X[0;0YIdentical Relations[133X[101X
[33X[0;0YLet [22Xw[122X be a word in free generators [22Xx_1,...,x_n[122X. A group [22XG[122X satisfies the
relation [22Xw=1[122X [13Xidentically[113X if each map from [22Xx_1,...,x_n[122X into [22XG[122X maps [22Xw[122X to the
identity element of [22XG[122X. We also say that [22XG[122X satisfies the [13Xidentical relation[113X
[22Xw=1[122X or satisfies the [13Xlaw[113X [22Xw=1[122X. In slight abuse of notation, we call the
elements [22Xx_1,...,x_n[122X [13Xidentical[113X generators.[133X
[33X[0;0YCommon examples of identical relations are: A group of nilpotency class at
most [22Xc[122X satisfies the law [22X[x_1,...,x_c+1]=1[122X. A group that satisfies the law
[22X[x,y,...,y]=1[122X where [22Xy[122X occurs [22Xn[122X-times, is called an [22Xn[122X-Engel group. A group
that satisfies the law [22Xx^d=1[122X is a group of exponent [22Xd[122X.[133X
[33X[0;0YTo describe finitely presented groups that satisfy one or more laws, we
extend a common notation for finitely presented groups by specifying the
identical generators as part of the generator list, separated from the group
generators by a semicolon: For example[133X
[24X[33X[0;6Y\langle a,b,c; x,y | x^5, [x,y,y,y]\rangle[133X
[124X
[33X[0;0Yis a group on 3 generators [22Xa,b,c[122X of exponent [22X5[122X satisfying the 3rd Engel law.
The presentation above is equivalent to a presentation on 3 generators with
an infinite set of relators, where the set of relators consists of all fifth
powers of words in the generators and all commutators [22X[x,y,y,y][122X where [22Xx[122X and
[22Xy[122X run through all words in the generators [22Xa,b,c[122X. The standalone programme
accepts the notation introduced above as a description of its input. In [5XGAP
4[105X finitely presented groups are specified in a different way, see
[2XNilpotentQuotient[102X ([14X3.1-1[114X) for a description.[133X
[33X[0;0YThis notation can also be used in words that mix group and identical
generators as in the following example:[133X
[24X[33X[0;6Y\langle a,b,c; x | [x,c], [a,x,x,x] \rangle[133X
[124X
[33X[0;0YThe first relator specifies a law which says that [22Xc[122X commutes with all
elements of the group. The second turns [22Xa[122X into a third right Engel element.[133X
[33X[0;0YAn element [22Xa[122X is called [13Xa right [22Xn[122X-th Engel element[113X or [13Xa right [22Xn[122X-Engel element[113X
if it satisfies the commutator law [22X[a,x,...,x]=1[122X where the identical
generator [22Xx[122X occurs [22Xn[122X-times. Likewise, an element [22Xb[122X is called an [13Xleft [22Xn[122X-th
Engel element[113X or [13Xleft [22Xn[122X-Engel element[113X if it satisfies the commutator law
[22X[x,b,b,...b]=1[122X.[133X
[33X[0;0YLet [22XG[122X be a nilpotent group. Then [22XG[122X satisfies a given law if the law is
satisfied by a certain finite set of instances given by Higman's Lemma, see
[Hig59]. The ANU NQ uses Higman's Lemma to obtain a finite presentation for
groups that satisfy one or several identical relations.[133X
[1X2.6 [33X[0;0YExpression Trees[133X[101X
[33X[0;0YExpressions involving commutators play an important role in the context of
nilpotent groups. Expanding an iterated commutator produces a complicated
and long expression. For example,[133X
[24X[33X[0;6Y[x,y,z] = y^{-1}x^{-1}yxz^{-1}x^{-1}y^{-1}xyz.[133X
[124X
[33X[0;0YEvaluating a commutator [22X[a,b][122X is done efficiently by computing the equation
[22X(ba)^-1ab[122X. Therefore, for each commutator we need to perform two
multiplications and one inversion. Evaluating [22X[x,y,z][122X needs four
multiplications and two inversions. Evaluation of an iterated commutator
with [22Xn[122X components takes [22X2n-1[122X multiplications and [22Xn-1[122X inversions. The
expression on the right hand side above needs [22X9[122X multiplications and [22X5[122X
inversions which is clearly much more expensive than evaluating the
commutator directly.[133X
[33X[0;0YAssuming that no cancellations occur, expanding an iterated commutator with
n components produces a word with [22X2^n+1-2^n-1-2[122X factors half of which are
inverses. A similar effect occurs whenever a compact expression is expanded
into a word in generators and inverses, for example [22X(ab)^49[122X.[133X
[33X[0;0YTherefore, it is important not to expand expressions into a word in
generators and inverses. For this purpose we provide a mechanism which we
call here [13Xexpression trees[113X. An expression tree preserves the structure of a
given expression. It is a (binary) tree in which each node is assigned an
operation and whose leaves are generators of a free group or integers. For
example, the expression [22X[(xy)^2, z][122X is stored as a tree whose top node is a
commutator node. The right subtree is just a generator node (corresponding
to [22Xz[122X). The left subtree is a power node whose subtrees are a product node on
the left and an integer node on the right. An expression tree can involve
products, powers, conjugates and commutators. However, the list of available
operations can be extended.[133X
[33X[0;0YEvaluation of an expression tree is done recursively and requires as many
operations as there are nodes in the tree. An expression tree can be
evaluated in a specific group by the function [2XEvaluateExpTree[102X ([14X3.2-2[114X).[133X
[33X[0;0YA presentation specified by expression trees is a record with the components
[11X.generators[111X and [11X.relations[111X. See section [14X3.2[114X for a description of the
functions that produce and manipulate expression trees.[133X

[1X2.7 [33X[0;0YA word about the implementation[133X[101X
[33X[0;0YThe ANU NQ is written in C, but not in ANSI C. I hope to make one of the
next versions ANSI compliable. However, it uses a fairly restricted subset
of the language so that it should be easy to compile it in new environments.
The code is 64-bit clean. If you have difficulties with porting it to a new
environment, let me know and I'll be happy to assist if time permits.[133X
[33X[0;0YThe program has two collectors: a simple collector from the left as
described in [LGS90] and a combinatorial from the left collector as
described in [VL90]. The combinatorial collector is always faster than the
simple collector, therefore, it is the collector used by this package by
default. This can be changed by modifying the global variable
[2XNqDefaultOptions[102X ([14X3.4-2[114X).[133X
[33X[0;0YIn a polycyclic group with generators that do not have power relations,
exponents may become arbitrarily large. Experience shows that this happens
rarely in the computations done by the ANU NQ. Exponents are represented by
32-bit integers. The collectors perform an overflow check and abort the
computation if an overflow occurred. In a GNU environment the program can be
compiled using the `long long' 64-bit integer type. For this uncomment the
relevant line in src/Makefile and recompile the program.[133X
[33X[0;0YAs part of the step that enforces consistency and the relations of the
group, the ANU NQ performs computations with integer matrices and converts
them to Hermite Normal Form. The algorithm used here is a variation of the
Kanan-Bachem algorithm based on the GNU multiple precision package GNU MP
[GMP]. Experience shows that the integer matrices are usually fairly sparse
and Kanan-Bachem seems to be sufficient in this context. However, the
implementation might benefit from a more efficient strategy for computing
Hermite Normal Forms. This is a topic for further investigations.[133X
[33X[0;0YAs the program does not compute the Smith Normal Form for each factor of the
lower central series but the Hermite Normal Form, it does not necessarily
obtain a minimal generating set for each factor of the lower central series.
The following is a simple example of this behaviour. We take the
presentation[133X
[24X[33X[0;6Y\langle x, y | x^2 = y \rangle[133X
[124X
[33X[0;0YThe group is clearly isomorphic to the additive group of the integers.
Applying the ANU NQ to this presentation gives the following nilpotent
presentation:[133X
[24X[33X[0;6Y\langle A,B | A^2 = B, [B,A] \rangle[133X
[124X
[33X[0;0YA nilpotent presentation on a minimal generating set would be the
presentation of the free group on one generator:[133X
[24X[33X[0;6Y\langle A | \; \rangle[133X
[124X
[1X2.8 [33X[0;0YThe input format of the standalone[133X[101X
[33X[0;0YThe input format for finite presentations resembles the way many people
write down a presentation on paper. Here are some examples of presentations
that the ANU NQ accepts:[133X
< a, b | > # free group of rank 2
< a, b, c; x, y |
[a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation
(a*[b,(a*c)])^6, # something that looks complicated
[x,y,y,y,y], # an identical relation
[c,x,x,x,x,x] # c is a fifth right Engel element
>
[33X[0;0YA presentation starts with '<' followed by a list of generators separated by
commas. Generator names are strings that contain only upper and lower case
letters, digits, dots and underscores and that do not start with a digit.
The list of generator names is separated from the list of relators/relations
by the symbol '[22X∣[122X'. The list of generators can be followed by a list of
identical generators separated by a semicolon. Relators and relations are
separated by commas and can be mixed arbitrarily. Parentheses can be used in
order to group subexpressions together. Square brackets can be used in order
to form left normed commutators. The symbols '*' and '^' can be used to form
products and powers, respectively. The presentation finishes with the symbol
'>'. A comment starts with the symbol '#' and finishes at the end of the
line. The file src/presentation.c contains a complete grammar for the
presentations accepted by the ANU NQ.[133X
[33X[0;0YTypically, the input for the standalone is put into a file by using a
standard text editor. The file can be passed as an argument to the function
[2XNilpotentQuotient[102X ([14X3.1-1[114X). It is also possible to put a presentation in the
standalone's input format into a string and use the string as argument for
[2XNilpotentQuotient[102X ([14X3.1-1[114X).[133X

[33X[0;0YThe parameter [11Xfp-group[111X is either a finitely presented group or a record
specifying a presentation by expression trees (see section [14X2.6[114X). The
parameter [11Xinput-file[111X is a string specifying the name of a file containing a
finite presentation in the input format (cf. section [14X2.8[114X) of the ANU NQ.
Such a file can be prepared by a text editor or with the help of the
function [2XNqStringFpGroup[102X ([14X3.3-2[114X).[133X
[33X[0;0YLet [22XG[122X be the group defined by [11Xfp-group[111X or the group defined in [11Xinput-file[111X.
The function computes a nilpotent presentation for [22XG/γ_c+1(G)[122X if the
optional parameter [11Xc[111X is specified. If [11Xc[111X is not given, then the function
attempts to compute the largest nilpotent quotient of [22XG[122X and it will
terminate only if [22XG[122X has a largest nilpotent quotient. See section [14X3.5[114X for a
possibility to follow the progress of the computation.[133X
[33X[0;0YThe optional argument [11Xid-gens[111X is a list of generators of the free group
underlying the finitely presented group [11Xfp-group[111X. The generators in this
list are treated as identical generators. Consequently, all relations of the
[11Xfp-group[111X involving these generators are treated as identical relations for
these generators.[133X
[33X[0;0YIn addition to the arguments explained above, the function accepts the
following options as shown in the first example below:[133X
[30X [33X[0;6Y[9Xgroup[109X This option can be used instead of the parameter [11Xfp-group[111X.[133X
[30X [33X[0;6Y[9Xinput\_string[109X This option can be used to specify a finitely presented
group by a string in the input format of the standalone program.[133X
[30X [33X[0;6Y[9Xinput\_file[109X This option specifies a file with input for the standalone
program.[133X
[30X [33X[0;6Y[9Xoutput\_file[109X This option specifies a file for the output of the
standalone.[133X
[30X [33X[0;6Y[9Xidgens[109X This options specifies a list of identical generators.[133X
[30X [33X[0;6Y[9Xclass[109X This option specifies the nilpotency class up to which the
nilpotent quotient will be computed.[133X
[33X[0;0YThe following example computes the class-5 quotient of the free group on two
generators.[133X

LowerCentralSeries takes no time.[133X

[33X[0;0YThe following example computes the relatively free fifth Engel group on two

corresponding quotient group. The quotient modulo the torsion subgroup is
torsion-free. Therefore, there is a nilpotent presentation without power
relations. The example computes a nilpotent presentation for the torsion
free factor group through the upper central series. The factors of the upper
central series in a torsion free group are torsion free. In this way one
obtains a set of generators of infinite order and the resulting nilpotent
presentation has no power relations.[133X

An old problem in the context of Engel elements is the question: Is a right \(n\)-Engel element left \(n\)-Engel? It is known that the answer is no. For details about the history of the problem, see [NN94]. In this paper the authors show that for \(n>4\) there are nilpotent groups with right \(n\)-Engel elements no power of which is a left \(n\)-Engel element. The insight was based on computations with the ANU NQ which we reproduce here. We also show the cases \(5>n\).

This shows that each right 2-Engel element in a finitely generated nilpotent group is a left 2-Engel element. Note that the group above is the largest nilpotent group generated by two elements, one of which is right 2-Engel. Every nilpotent group generated by an arbitrary element and a right 2-Engel element is a homomorphic image of the group \(H\).

General remarks
In this chapter we define notation used throughout this manual and
recollect basic facts about nilpotent groups. We also provide some
background information about the functionality implemented in this
package.
Commutators and the Lower Central Seriescommutator The commutator of two elements
h_1 and h_2 of a group G is the element
h_1^{-1}h_2^{-1}h_1h_2 and is denoted by [h_1,h_2].
It satisfies the equation h_1h_2 = h_2h_1[h_1,h_2] and
can be interpreted as the correction term that has to be introduced
into a word if two elements of a group are interchanged.
Iterated commutators are written in left-normed fashion:
left-normed commutator[h_1,h_2,\ldots,h_{n-1},h_n]=[[h_1,h_2,\ldots,h_{n-1}],h_n].
lower central series
The lower central series of G is defined inductively
as \gamma_1(G) = G, \gamma_i(G) = [\gamma_{i-1}(G),G] for
i \ge 2. Each term in the lower central series is a normal
(even fully invariant) subgroup of G. The factors of the
lower central series are abelian groups. On each factor the induced
action of G via conjugation is the trivial action.
The factor \gamma_k(G)/\gamma_{k+1}(G) is generated by
the elements [g,h]\gamma_{k+1}(G), where g runs
through a set of (representatives of) generators for
G/\gamma_2(G) and h runs through a set of
(representatives of) generators for
\gamma_{k-1}(G)/\gamma_k(G). Therefore, each factor of the
lower central series is finitely generated if G is finitely
generated.
If one factor of the lower central series is finite, then all
subsequent factors are finite. Then the exponent of the
k+1-th factor is a divisor of the exponent of the k-th
factor of the lower central series. In particular, the exponents of
all factors of the lower central series are bounded by the
exponent of the first finite factor of the lower central series.
Nilpotent groupsnilpotent
A group G is called nilpotent if there is a positive
integer c such that all (c+1)-fold commutators are
trivial in G. The smallest integer with this property is
called the
nilpotency classclassnilpotency class of G. In terms of the lower
central series a group G \not= 1 has nilpotency class c
if and only if
\gamma_{c}(G) \not= 1 and \gamma_{c+1}(G) = 1.
Examples of nilpotent groups are finite p-groups, the
group of unitriangular matrices over a ring with one and the factor
groups of a free group modulo the terms of its lower central
series.
Finiteness of a nilpotent group can be decided by the group's
commutator factor group. A nilpotent group is finite if and only if
its commutator factor group is finite. A group whose commutator
factor group is finite can only have finite nilpotent quotient
groups.
By refining the lower central series of a finitely generated
nilpotent group one can obtain a (sub)normal series
G_1>G_2>...>G_{k+1}=1 with cyclic (central) factors.
Therefore, every finitely generated nilpotent group is
polycyclicpolycyclic. Such a polycyclic
series gives rise to a polycyclic generating
sequence polycyclic generating sequence by choosing a
generator a_i for each cyclic factor G_i/G_{i+1}.
Let I be the
set of indices such that G_i/G_{i+1} is finite. A simple
induction argument shows that every element of the group can be
written uniquely as a normal worda_1^{e_1}\ldots
a_n^{e_n} with integers e_i and 0\leq e_i<m_i
for i\in I.
Nilpotent presentations
From a polycyclic generating sequence one can obtain a
polycyclic presentationpolycyclic
presentation for the group. The following set of power and
commutator relations is a defining set of relations. The
power relationpower relations express
a_i^{m_i} in terms of the generators
a_{i+1},\ldots,a_n whenever G_i/G_{i+1} is finite with
order m_i. The commutator relationcommutator relations are obtained by expressing
[a_j,a_i] for j>i as a word in the generators
a_{i+1},\ldots,a_n. If the polycyclic series is obtained
from refining the lower central series, then [a_j,a_i] is
even a word in a_{j+1},\ldots,a_n. In this case we obtain a
nilpotent presentation.
To be more precise, a nilpotent presentationnilpotent presentation is given on a finite number of
generators a_1,\ldots,a_n. Let I be the set of
indices such that G_i/G_{i+1} is finite. Let m_i be
the order of G_i/G_{i+1} for i\in I. Then a nilpotent
presentation has the form
\langle a,\ldots,a_n |
a_i^{m_i} = w_{ii}(a_{i+1},\ldots,a_n)
\mbox{ for } i\in I;\;
[a_j,a_i] = w_{ij}(a_{j+1},\ldots,a_n)
\mbox{ for } 1\leq i < j\leq n\rangle
Here, w_{ij}(a_k,\ldots,a_n) denotes a group word in the
generators a_k,\ldots,a_n.
In a group given by a polycyclic presentation each element in
the group can be written as a normal worda_1^{e_1}\ldots
a_n^{e_n} with e_i \in \mathbb{Z} and 0 \leq e_i < m_i
for i \in I. A procedure called collection can be
used to convert an arbitrary word in the generators into an
equivalent normal word. In general, the resulting normal word need
not be unique. The result of collecting a word may depend on the
steps chosen during the collection procedure. A polycyclic
presentation with the property that two different normal words are
never equivalent is called
consistentconsistent. A polycyclic
presentation derived from a polycyclic series as above is
consistent. The following example shows an inconsistent polycyclic
presentation
\langle a,b\mid a^2, b^a = b^2 \rangle
as b = baa = ab^2a = a^2b^4 = b^4 which implies b^3=1.
Here we have the equivalent normal words b^3 and the empty
word. It can be proved that consistency can be checked by
collecting a finite number of words in the given generating set in
two essentially different ways and checking if the resulting normal
forms are the same in both cases. See Chapter 9 of the book for an introduction to polycyclic groups and
polycyclic presentations.
For computations in a polycyclic group one chooses a consistent
polycyclic presentation as it offers a simple solution to the word
problem: Equality between two words is decided by collecting both
words to their respective normal forms and comparing the normal
forms. Nilpotent groups and nilpotent presentations are special
cases of polycyclic groups and polycyclic presentations. Nilpotent
presentations allow specially efficient collection methods. The
package Polycyclic provides algorithms to compute
with polycyclic groups given by a polycyclic presentation.
However, inconsistent nilpotent presentations arise naturally in
the nilpotent quotient algorithm. There is an algorithm based on
the test words for consistency mentioned above to modify the arising
inconsistent presentations suitably to obtain a consistent one for
the same group.
A sketch of the algorithm
The input for the ANU NQ in its simplest form is a finite
presentation \langle X|R\rangle for a group G. The
first step of the algorithm determines a nilpotent presentation for
the commutator quotient of G. This is a presentation of the
class-1 quotient of G. Call its generators
a_1,...,a_d. It also determines a homomorphism of G
onto the commutator quotient and describes it by specifying the
image of each generator in X as a word in the a_i.
For the general step assume that the algorithm has computed a
nilpotent presentation for the class-c quotient of G
and that a_1,...,a_d are the generators introduced in the
first step of the algorithm. Furthermore, there is a map from X
into the class-c quotient describing the epimorphism from
G onto G/\gamma_{c+1}(G).
Let b_1,...b_k be the generators from the last step of the
algorithm, the computation of \gamma_c(G)/\gamma_{c+1}(G).
This means that b_1,...b_k generate
\gamma_c(G)/\gamma_{c+1}(G). Then the commutators
[b_j,a_i] generate \gamma_{c+1}(G)/\gamma_{c+2}(G).
The algorithm introduces new, central generators c_{ij} into
the presentation, adds the relations [b_j,a_i] = c_{ij} and
modifies the existing relations by appending suitable words in the
c_{ij}, called tails, to the right hand sides of the
power and commutator relations. The resulting presentation is a
nilpotent presentation for the nilpotent cover of
G/\gamma_{c+1}(G). The nilpotent cover is the largest central
extension of G/\gamma_{c+1}(G) generated by d elements.
It is is uniquely determined up to isomorphism.
The resulting presentation of the nilpotent cover is in general
inconsistent. Consistency is achieved by running the consistency
test. This results in relations among the generators
c_{ij} which can be used to eliminate some of those
generators or introduce power relations. After this has been done
we have a consistent nilpotent presentation for the nilpotent cover
of G/\gamma_{c+1}(G).
Furthermore, the nilpotent cover need not satisfy the relations
of G. In other words, the epimorphism from G onto
G/\gamma_{c+1}(G) cannot be lifted to an epimorphism onto the
nilpotent cover. Applying the epimorphism to each relator of
G and collecting the resulting words of the nilpotent cover
yields a set of words in the c_{ij}. This gives further
relations between the c_{ij} which leads to further
eliminations or modifications of the power relations for the
c_{ij}.
After this, the inductive step of the ANU NQ is complete and a
consistent nilpotent presentation for G/\gamma_{c+2}(G) is
obtained together with an epimorphism from G onto the
class-(c+1) quotient.
Chapter 11 of the book discusses a
nilpotent quotient algorithm. A description of the implementation
in the ANU NQ is contained in
Identical Relations
Let w be a word in free generators x_1,\ldots,x_n. A
group G satisfies the relation w=1identically if
each map from x_1,\ldots,x_n into G maps w to
the identity element of G. We also say that G satisfies the
identical relationlawidentical
relationw=1 or satisfies the laww=1. In
slight abuse of notation, we call the elements x_1,\ldots,x_nidentical generatoridentical generators.
Common examples of identical relations are: A group of
nilpotency class at most c satisfies the law
[x_1,\ldots,x_{c+1}]=1. A group that satisfies the law
[x,y,\ldots,y]=1 where y occurs n-times, is
called an n-Engel group. A group that satisfies the law
x^d=1 is a group of exponent d.
To describe finitely presented groups that satisfy one or more laws,
we extend a common notation for finitely presented groups
by specifying the identical generators as part of the generator
list, separated from the group generators by a semicolon: For
example
\langle a,b,c; x,y | x^5, [x,y,y,y]\rangle
is a group on 3 generators a,b,c of exponent 5
satisfying the 3rd Engel law. The presentation above is equivalent
to a presentation on 3 generators with an infinite set of relators,
where the set of relators consists of all fifth powers of words in
the generators and all commutators [x,y,y,y] where x
and y run through all words in the generators a,b,c.
The standalone programme accepts the notation introduced above as a
description of
its input. In GAP 4 finitely presented groups
are specified in a different way, see
for a description.
This notation can also be used in words that mix group and identical
generators as in the following example:
\langle a,b,c; x | [x,c], [a,x,x,x] \rangle
The first relator specifies a law which says that c commutes
with all elements of the group. The second turns a into a
third right Engel element.
An element a is called a right n-th
Engel element or a right n-Engel elementright Engel element
if it satisfies the commutator law [a,x,...,x]=1
where the identical generator x occurs n-times.
Likewise, an element b is called an left n-th Engel
element or left n-Engel elementleft Engel element
if it satisfies the commutator law [x,b,b,...b]=1.
Let G be a nilpotent group. Then G satisfies a
given law if the law is satisfied by a certain finite set of
instances given by Higman's Lemma, see . The
ANU NQ uses Higman's Lemma to obtain a finite presentation for
groups that satisfy one or several identical relations.
Expression Trees
Expressions involving commutators play an important role in the
context of nilpotent groups. Expanding an iterated commutator
produces a complicated and long expression. For example,
[x,y,z] = y^{-1}x^{-1}yxz^{-1}x^{-1}y^{-1}xyz.
Evaluating a commutator [a,b] is done efficiently by
computing the equation (ba)^{-1}ab. Therefore, for each
commutator we need to perform two multiplications and one inversion.
Evaluating [x,y,z] needs four multiplications and two
inversions. Evaluation of an iterated commutator with n
components takes 2n-1 multiplications and
n-1 inversions. The expression on the right hand side above
needs 9 multiplications and 5 inversions which is
clearly much more expensive than evaluating the commutator directly.
Assuming that no cancellations occur, expanding an iterated
commutator with n components produces a word with
2^{n+1}-2^{n-1}-2 factors half of which are inverses. A
similar effect occurs whenever a compact expression is expanded into
a word in generators and inverses, for example (ab)^{49}.
Therefore, it is important not to expand expressions into a
word in generators and inverses. For this purpose we provide a
mechanism which we call here
expression treesexpression trees. An expression tree preserves the
structure of a given expression. It is a (binary) tree in which
each node is assigned an operation and whose leaves are generators
of a free group or integers. For example, the expression
[(xy)^2, z] is stored as a tree whose top node is a
commutator node. The right subtree is just a generator node
(corresponding to z). The
left subtree is a power node whose subtrees are a
product node on the left and an integer node on the right. An
expression tree can involve products, powers, conjugates and
commutators. However, the list of available operations can
be extended.
Evaluation of an expression tree is done recursively and
requires as many operations as there are nodes in the tree. An
expression tree can be evaluated in a specific group by the function
.
A presentation specified by expression trees is a record with
the components .generators and .relations. See
section for a description of the functions
that produce and manipulate expression trees.

A word about the implementation
The ANU NQ is written in C, but not in ANSI C. I hope to make one
of the next versions ANSI compliable. However, it uses a fairly
restricted subset of the language so that it should be easy to
compile it in new environments. The code is 64-bit clean. If you
have difficulties with porting it to a new environment, let me know
and I'll be happy to assist if time permits.
The program has two collectors: a simple collector from the left
as described in and a combinatorial from the left
collector as described in . The combinatorial
collector is always faster than the simple collector, therefore, it
is the collector used by this package by default. This can be
changed by modifying the global variable .
In a polycyclic group with generators that do not have power
relations, exponents may become arbitrarily large. Experience shows
that this happens rarely in the computations done by the ANU NQ.
Exponents are represented by 32-bit integers. The collectors
perform an overflow check and abort the computation if an overflow
occurred. In a GNU environment the program can be compiled using
the `long long' 64-bit integer type. For this uncomment the
relevant line in src/Makefile and recompile the program.
As part of the step that enforces consistency and the relations
of the group, the ANU NQ performs computations with integer matrices
and converts them to Hermite Normal Form. The algorithm used here
is a variation of the Kanan-Bachem algorithm based on the GNU
multiple precision package GNU MP . Experience shows
that the integer matrices are usually fairly sparse and Kanan-Bachem
seems to be sufficient in this context. However, the implementation
might benefit from a more efficient strategy for computing Hermite
Normal Forms. This is a topic for further investigations.
As the program does not compute the Smith Normal Form for each
factor of the lower central series but the Hermite Normal
Form, it does not necessarily obtain a minimal generating set for
each factor of the lower central series. The following is a simple
example of this behaviour. We take the presentation
\langle x, y | x^2 = y \rangle
The group is clearly isomorphic to the additive group of the
integers. Applying the ANU NQ to this presentation gives the
following nilpotent presentation:
\langle A,B | A^2 = B, [B,A] \rangle
A nilpotent presentation on a minimal generating set would be the
presentation of the free group on one generator:
\langle A | \; \rangle
The input format of the standalone
The input format for finite presentations resembles the way many
people write down a presentation on paper. Here are some examples of
presentations that the ANU NQ accepts:
# free group of rank 2
< a, b, c; x, y |
[a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation

A presentation starts with '&tlt;' followed by a list of generators
separated by commas. Generator names are strings that contain only
upper and lower case letters, digits, dots and underscores and that do
not start with a digit. The list of generator names is separated from
the list of relators/relations by the symbol '\mid'. The list of
generators can be followed by a list of identical generators separated
by a semicolon. Relators and relations are separated by commas and
can be mixed arbitrarily. Parentheses can be used in order to group
subexpressions together. Square brackets can be used in order to form
left normed commutators. The symbols '*' and '&circum;' can be
used to form products and powers, respectively. The presentation
finishes with the symbol '&tgt;'. A comment starts with the symbol '&hash;'
and finishes at the end of the line. The file src/presentation.c
contains a complete grammar for the presentations accepted by the ANU
NQ.
Typically, the input for the standalone is put into a file by
using a standard text editor. The file can be passed as an argument
to the function . It is
also possible to put a presentation in the standalone's input format
into a string and use the string as argument for .

[1X4.1 [33X[0;0YRight Engel elements[133X[101X
[33X[0;0YAn old problem in the context of Engel elements is the question: Is a right
[22Xn[122X-Engel element left [22Xn[122X-Engel? It is known that the answer is no. For details
about the history of the problem, see [NN94]. In this paper the authors show
that for [22Xn>4[122X there are nilpotent groups with right [22Xn[122X-Engel elements no power
of which is a left [22Xn[122X-Engel element. The insight was based on computations
with the ANU NQ which we reproduce here. We also show the cases [22X5>n[122X.[133X

[33X[0;0YThis shows that each right 2-Engel element in a finitely generated nilpotent
group is a left 2-Engel element. Note that the group above is the largest
nilpotent group generated by two elements, one of which is right 2-Engel.
Every nilpotent group generated by an arbitrary element and a right 2-Engel
element is a homomorphic image of the group [22XH[122X.[133X

[1X5 [33X[0;0YInstallation of the Package[133X[101X
[33X[0;0YInstallation of the ANU NQ is done in two steps.[133X
[1X5.1 [33X[0;0YConfiguring for compilation[133X[101X
[33X[0;0YFirst the configure script is run:[133X
[4X[32X Installation [32X[104X
[4X ./configure [104X
[4X[32X[104X
[33X[0;0YIf you installed the package in another [21X[11Xpkg[111X[121X directory than the standard [21X[11Xpkg[111X[121X
directory in your [5XGAP[105X 4 installation, then you have to do two things.
Firstly during compilation you have to use the option [10X--with-gaproot=PATH[110X of
the [11Xconfigure[111X script where [21XPATH[121X is a path to the main [5XGAP[105X root directory (if
not given the default [21X[11X../..[111X[121X is assumed). That is, run[133X
[4X[32X Installation [32X[104X
[4X ./configure --with-gaproot=PATH [104X
[4X[32X[104X
[33X[0;0YSecondly you have to specify the path to the directory containing your [21X[11Xpkg[111X[121X
directory to [5XGAP[105X's list of directories. This can be done by starting [5XGAP[105X
with the [21X[11X-l[111X[121X command line option followed by the name of the directory and a
semicolon. Then your directory is prepended to the list of directories
searched. Otherwise the package is not found by [5XGAP[105X. Of course, you can add
this option to your [5XGAP[105X startup script.[133X
[33X[0;0YAnother issue that can occur when running [11Xconfigure[111X is that it may fail to
locate the the GNU multiple precision library (GMP [GMP]) which ANU NQ
requires to work. This library is also used by [5XGAP[105X and hence normally should
be available on your system anyway. But if this is not the case for some
reason, it has to be installed first. A copy of GMP can be obtained from
[7Xhttp://gmplib.org/[107X.[133X
[33X[0;0YIn order for the [11Xconfigure[111X script to find your copy of GMP, you may have
tell it where to find it via [10X--with-gmp=PATH[110X, where [21XPATH[121X is the path where
GMP was installed:[133X
[4X[32X Installation [32X[104X
[4X ./configure --with-gmp=PATH [104X
[4X[32X[104X

GAP (nq) - Chapter 1: Introduction
This package provides an interface between GAP 4 and the Australian National University Nilpotent Quotient Program (ANU NQ). The ANU NQ was implemented as part of the author's work towards his PhD at the Australian National University, hence the name of the program. The program takes as input a finite presentation of a group and successively computes factor groups modulo the terms of the lower central series of the group. These factor groups are computed in terms of polycyclic presentations.
The ANU NQ is implemented in the programming language C. The implementation has been developed in a Unix environment and Unix is currently the only operating system supported. It runs on a number of different Unix versions, e.g. Solaris and Linux.
For integer matrix computations it relies on the GNU MP [GMP] package and requires this package to be installed on your system.
This package relies on the functionality for polycyclic groups provided by the GAP package polycyclic[EN02] and requires the package polycyclic to be installed as a GAP package on your computer system.
Comments, bug reports and suggestions are very welcome, please submit them via our issue tracker.
This manual contains references to parts of the GAP Reference Manual which are typeset in a slightly idiosyncratic way. The following example shows how such references are printed: 'For further information on creating a free group see FreeGroup (Reference: FreeGroup).' The text in bold face refers to the GAP Reference Manual.
Each item in the list of references at the end of this manual is followed by a list of numbers that specify the pages of the manual where the reference occurs.
If you installed the package in another "pkg" directory than the standard "pkg" directory in your GAP 4 installation, then you have to do two things. Firstly during compilation you have to use the option --with-gaproot=PATH of the configure script where "PATH" is a path to the main GAP root directory (if not given the default "../.." is assumed). That is, run
./configure --with-gaproot=PATH
Secondly you have to specify the path to the directory containing your "pkg" directory to GAP's list of directories. This can be done by starting GAP with the "-l" command line option followed by the name of the directory and a semicolon. Then your directory is prepended to the list of directories searched. Otherwise the package is not found by GAP. Of course, you can add this option to your GAP startup script.
Another issue that can occur when running configure is that it may fail to locate the the GNU multiple precision library (GMP [GMP]) which ANU NQ requires to work. This library is also used by GAP and hence normally should be available on your system anyway. But if this is not the case for some reason, it has to be installed first. A copy of GMP can be obtained from http://gmplib.org/.
In order for the configure script to find your copy of GMP, you may have tell it where to find it via --with-gmp=PATH, where "PATH" is the path where GMP was installed:
./configure --with-gmp=PATH
Yf necessary, you may combine --with-gmp and --with-gaproot.
5.2 Compiling the nq binary
If configure reports no problems, the next step is to start the compilation:
make
A compiled version of the program named nq is then placed into the directory bin/<complicated name>. The <complicated name> component encodes the operating system and the compiler used. This allows you to compile NQ on several architectures sharing the same files system.
If there are any warnings or even fatal error messages during the compilation process, please submit a bug report about that following the instructions in Section 5.4
5.3 Testing
After the compilation is finished you can check if the ANU NQ is running properly on your system. Simply type
make test
This runs some computations and compares their output with the output files in the directory examples. If any errors are reported, please follow the instructions below.
5.4 Feedback
If you encounter problems with any of the above steps, please do not hesitate to contact us about this. You can either use the nq issue tracker or contact the GAP support group via support@gap-system.org. Please make sure to include information about the specific issue you encountered (e.g. steps to reproduce it, the specific error message), your operating system, the compiler you used and also the versions of GAP and this package that were involved.

[33X[0;0YAll parameters in square brackets are optional. The parameter
has to be the name of a file that contains a finite group presentation for
which a nilpotent quotient is to be calculated. This file name must not
start with a digit. If it is not present, nq will read the presentation from
standard input. The parameter restricts the computation of the
nilpotent quotient to at most that (nilpotency) class, i.e. the program
calculates the quotient group of the [22X(c+1)[122X-th term of the lower central
series. If is omitted, the program computes successively the factor
groups of the lower central series of the given group. If there is a largest
nilpotent quotient, i.e., if the lower central series becomes constant, the
program will eventually terminate with the largest nilpotent quotient. If
there is no largest nilpotent quotient, the program will run forever (or
more precisely will run out of resources). On termination the program prints
a nilpotent presentation for the nilpotent quotient it has computed. The
options -l, -r and -e can be used to enforce Engel conditions on the
nilpotent quotient to be calculated. All these options have to be followed
by a positive integer . Their meaning is the following:[133X
[8X-n [108X
[33X[0;6YThis option forces the first k generators to be left or right Engel
element if also the option -l or -r (or both) is present. Otherwise it
is ignored.[133X
[8X-l [108X
[33X[0;6YThis forces the first k generators [22Xg_1,...,g_k[122X of the nilpotent
quotient Q to be left n-Engel elements, i.e., they satisfy
[22X[x,...,x,g_i] = 1[122X (x occurring n-times) for all x in Q and [22X1 <= i <=
k[122X. If the option -n is not used, then k = 1.[133X
[8X-r [108X
[33X[0;6YThis forces the first k generators [22Xg_1,...,g_k[122X of the nilpotent
quotient Q to be right n-Engel elements,i.e., they satisfy
[22X[g_i,x,..,x] = 1[122X (x occurring n-times) for all x in Q and [22X1 <= i <= k[122X.
If the option -n is not used, then k = 1.[133X
[8X-e [108X
[33X[0;6YThis enforces the n-th Engel law on Q, i.e., [22X[x,y,..,y] = 1[122X (y
occurring n-times) for all x,y in Q.[133X
[8X-t [108X
[33X[0;6YThis option specifies how much CPU time the program is allowed to use.
It will terminate after seconds of CPU time. If is followed
(without space) by one of the letters m, h or d, specifies the
time in minutes, hours or days, respectively.[133X
[33X[0;0YThe other options have the following meaning. Care has to be taken when the
options -s or -c are used since the resulting nilpotent quotient need NOT
satisfy the required Engel condition. The reason for this is that a smaller
set of test words is used if one of these two options are present. Although
this smaller set of test words seems to be sufficient to enforce the
required Engel condition, this fact has not been proven.[133X
[8X-a[108X
[33X[0;6YFor each factor of the lower central series a file is created in the
current directory that contains an integer matrix describing the
factor as abelian group. The first number in that file is the number
of columns of the matrix. Then the matrix follows in row major order.
The matrix for the i-th factor is put into the file

[33X[0;6Ytoggles printing of the pc presentation for the nilpotent quotient at
the end of a calculation.[133X
[8X-s[108X
[33X[0;6YThis option causes the program to check only semigroup words in the
generating set of the nilpotent quotient when an Engel condition is
enforced. If none of the options -l, -r or -e are present, it is
ignored.[133X
[8X-f[108X
[33X[0;6YThis option causes to check semiwords in the generating set of the
nilpotent quotient first and then all other words that need to be
checked. It is ignored if the option -s is used or none of the options
-l, -r or -e are present.[133X
[8X-c[108X
[33X[0;6YThis option stops checking the Engel law at each class if all the
checks of a certain weight did not yield any non-trivial instances of
the law.[133X

increased weight. This flag reverses the order.[133X

[33X[0;6YProduce GAP output. Presently the GAP output consists only of a
sequence of integer matrices whose rows are relations of the factors
of the lower central series as abelian groups. This will change as
soon as GAP can handle infinite polycyclic groups.[133X
[8X-E[108X
[33X[0;6Ythe *last* n generators are Engel generators. This works in
conjunction with option -n.[133X
[8X-m[108X

series. The matrices are written to files with the names 'matrix.'
where is replaced by the number of the factor in the lower
central series. Each file contains first the number of columns of the
matrix and then the rows of the matrix. The matrix is written as each
relation is produced and is not in upper triangular form.[133X
[8X-M[108X
[33X[0;6Youtput the relation matrix before and after relations have been
enforced. This results in two groups of files with names
'.nilp.' and '.mult.' where is the name of
the input files and is the class. The matrices are in upper
triangular form.[133X
[1XA.2 [33X[0;0YThe input format for presentations[133X[101X
[33X[0;0YThe input format for finite presentations resembles the way many people
write down a presentation on paper. Here are some examples of presentations
that the ANU NQ accepts:[133X
< a, b | > # free group of rank 2
< a, b, c | [a,b,c], # a left normed commutator
[b,c,c,c]^6, # another one raised to a power
a^2 = c^-3*a^2*c^3, # a relation
a^(b*c) = a, # a conjugate relation
(a*[b,(a*c)])^6 # something that looks complicated
>
[33X[0;0YA presentation starts with '<' followed be a list of generators separated by
commas. Generator names are strings that contain only upper and lower case
letters, digits, dots and underscores and that do not start with a digit.
The list of generator names is separated from the list of relators/relations
by the symbol '|'. Relators and relations are separated by commas and can be
mixed arbitrarily. Parentheses can be used in order to group subexpressions
together. Square brackets can be used in order to form left normed
commutators. The symbols '*' and '^' can be used to form products and
powers, respectively. The presentation finishes with the symbol '>'. A
comment starts with the symbol '#' and finishes at the end of the line. The
file src/presentation.c contains a complete grammar for the presentations
accepted by the ANU NQ.[133X
[1XA.3 [33X[0;0YAn example[133X[101X
[33X[0;0YLet G be the free group on two generators x and y. The input file (called
free2.fp here) contains the following:[133X

[33X[0;0YMost of the comments are fairly self-explanatory. One note of caution is
necessary: The number of generators for each factor of the lower central
series is not the minimal number possible but is the number of generators
that the ANU NQ chose to use. This will be improved in one of the future
version of the program. The epimorphism from the original group onto the
nilpotent quotient is printed in a somewhat confusing way. The generators on
the left hand side of the arrows correspond to the generators in the
original presentation but are printed with different names. This will be
fixed in one of the next version.[133X
[1XA.4 [33X[0;0YSome remarks about the algorithm[133X[101X
[33X[0;0YThe implementation of the algorithm is fairly straight forward. The program
uses a weighted nilpotent presentation with definitions to represent a
nilpotent group. Calculations in the nilpotent group are done using a
collector from the left without combinatorial collection. Generators for the
[22Xc[122X-th lower central factor are defined as commutators of the form [22X[y,x][122X,
where [22Xx[122X is a generator of weight 1 and [22Xy[122X is a generator of weight [22Xc-1[122X. Then
the program calculates the necessary changes (tails) for all relations which
are not definitions, runs through the consistency check and evaluates the
original relations on the polycyclic presentation. This gives a list of
words, which have to be made trivial in order to obtain a consistent
polycyclic presentation representing a nilpotent quotient of the given
finitely presented group. This list is converted into a integer matrix,
which is transformed into upper triangular form using the Kannan-Bachem
algorithm. The GNU multiple precision package is used for this.[133X

** Commute: This seems to be the most difficult data structure because
** its entries are difficult to compute. `Commute[i]' is the
** first generator for which the collector from the left has
** to do something when the i-th generator is moved to its
** correct place. In other words, the collector starts at
** `Commute[i]' in the exponent vector when the i-th generator
** is moved to its place. The length of `Commute' is `NrPcGens'+1.
** CommuteList: This array holds a list of different versions of
** Commute[]. They are used for fast evaluation of iterated
** commutators, as for example Engel conditions. CommuteList[c]
** is Commute[] as if the current group had class c.
** Exponent: This array containes the exponents for the power relation
** of each generator. If the generator i does not have a power
** relation, `Exponents[i]' is zero. The length of `Exponents'
** is `NrPcGens'+1.
** Power: This array contains the right hand sides of the power
** relation. If a generator does not have a power relation, the
** corresponding entry in `Powers' is a null pointer.
** Conjugate: This 2-dimensional array contains the right hand sides

\`configure' configures ANU Nilpotent Quotient Program 2.5.4 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/nq]

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-silent-rules less verbose build output (undo: "make V=1")
--disable-silent-rules verbose build output (undo: "make V=0")
--enable-maintainer-mode
enable make rules and dependencies not useful (and
sometimes confusing) to the casual installer
--enable-shared[=PKGS] build shared libraries [default=yes]
--enable-static[=PKGS] build static libraries [default=yes]
--enable-fast-install[=PKGS]
optimize for fast installation [default=yes]
--enable-dependency-tracking
do not reject slow dependency extractors
--disable-dependency-tracking
speeds up one-time build
--disable-libtool-lock avoid locking (might break parallel builds)
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
both]
--with-aix-soname=aix|svr4|both
shared library versioning (aka "SONAME") variant to
provide on AIX, [default=aix].
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-sysroot[=DIR] Search for dependent libraries within DIR (or the
compiler's sysroot if not specified).
--with-gaproot= specify root of GAP installation
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
LT_SYS_LIBRARY_PATH
User-defined run-time library search path.
CPP C preprocessor
ABI Set this equal to 32 or 64 to build nq in 32- or 64-bit mode.
The default value for this option is determined by testing the
behaviour of your compiler, so should be 32 on a 32-bit system
and 64 on one which is 64-bit.
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Oops!
Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard:
Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message. This
can help us improve future automake versions.

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: .
If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

# Using Import Files as archive members, it is possible to support
# filename-based versioning of shared library archives on AIX. While
# this would work for both with and without runtime linking, it will
# prevent static linking of such archives. So we do filename-based
# shared library versioning with .so extension only, which is used
# when both runtime linking and shared linking is enabled.
# Unfortunately, runtime linking may impact performance, so we do
# not want this to be the default eventually. Also, we use the
# versioned .so libs for executables only if there is the -brtl
# linker flag in LDFLAGS as well, or --with-aix-soname=svr4 only.
# To allow for filename-based versioning support, we need to create
# libNAME.so.V as an archive file, containing:
# *) an Import File, referring to the versioned filename of the
# archive as well as the shared archive member, telling the
# bitwidth (32 or 64) of that shared object, and providing the
# list of exported symbols of that shared object, eventually
# decorated with the 'weak' keyword
# *) the shared object with the F_LOADONLY flag set, to really avoid
# it being seen by the linker.
# At run time we better use the real file rather than another symlink,
# but for link time we create the symlink libNAME.so -> libNAME.so.V

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard:

of your $PATH and any error possibly output before this message. This

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation

to "yes", and re-run configure.

# results into a variable named after the function, and often use
# temporary variables in the '^_G_' namespace. If you are careful to
# avoid using those namespaces casually in your sourcing script, things
# should continue to work as you expect. And, of course, you can freely
# overwrite any of the functions or variables defined here before

## ------ ##
## Usage. ##
## ------ ##
# This file is a library for parsing options in your shell scripts along
# with assorted other useful supporting features that you can make use
# of too.
#
# For the simplest scripts you might need only:
#
# #!/bin/sh
# . relative/path/to/funclib.sh
# . relative/path/to/options-parser
# scriptversion=1.0
# func_options ${1+"$@"}
# eval set dummy "$func_options_result"; shift
# ...rest of your script...
#
# In order for the '--version' option to work, you will need to have a
# suitably formatted comment like the one at the top of this file
# starting with '# Written by ' and ending with '# warranty; '.
#
# For '-h' and '--help' to work, you will also need a one line
# description of your script's purpose in a comment directly above the
# '# Written by ' line, like the one at the top of this file.
#
# The default options also support '--debug', which will turn on shell
# execution tracing (see the comment above debug_cmd below for another
# use), and '--verbose' and the func_verbose function to allow your script
# to display verbose messages only when your user has specified
# '--verbose'.
#
# After sourcing this file, you can plug processing for additional
# options by amending the variables from the 'Configuration' section
# below, and following the instructions in the 'Option parsing'
# section further down.
## -------------- ##
## Configuration. ##
## -------------- ##
# You should override these variables in your script after sourcing this
# file so that they reflect the customisations you have added to the
# option parser.
# The usage line for option parsing errors and the start of '-h' and
# '--help' output messages. You can embed shell variables for delayed
# expansion at the time the message is displayed, but you will need to
# quote other shell meta-characters carefully to prevent them being
# expanded when the contents are evaled.
usage='$progpath [OPTION]...'
# Short help message in response to '-h' and '--help'. Add to this or
# override it after sourcing this library to reflect the full set of
# options your script accepts.
usage_message="\
--debug enable verbose shell tracing
-W, --warnings=CATEGORY
report the warnings falling in CATEGORY [all]
-v, --verbose verbosely report processing
--version print version information and exit
-h, --help print short or long help message and exit
"
# Additional text appended to 'usage_message' in response to '--help'.
long_help_message="
Warning categories include:
'all' show all warnings
'none' turn off all the warnings
'error' warnings are treated as fatal errors"
# Help message printed before fatal option parsing errors.

# In each case, ARG is the path to be converted from $build to $host format.
# The result will be available in $func_to_host_path_result.
#
# Path separators are also converted from $build format to $host format. If
# ARG begins or ends with a path separator character, it is preserved (but
# converted to $host format) on output.
#
# All path conversion functions are named using the following convention:
# file name conversion function : func_convert_file_X_to_Y ()
# path conversion function : func_convert_path_X_to_Y ()
# where, for any given $build/$host combination the 'X_to_Y' value is the
# same. If conversion functions are added for new $build/$host combinations,
# the two new functions must follow this pattern, or func_init_to_host_path_cmd
# will break.
# func_init_to_host_path_cmd

-no-fast-install disable the fast-install mode
-no-install link a not-installable executable
-no-undefined declare that a library does not refer to external symbols
-o OUTPUT-FILE create OUTPUT-FILE from the specified objects
-objectlist FILE use a list of object files found in FILE to specify objects
-os2dllname NAME force a short DLL name on OS/2 (no effect on other OSes)

Every other argument is treated as a filename. Files ending in '.la' are
treated as uninstalled libtool libraries, other files are standard or library
object files.
If the OUTPUT-FILE ends in '.la', then a libtool library is created,
only library objects ('.lo' files) may be specified, and '-rpath' is
required, except when creating a convenience library.
If OUTPUT-FILE ends in '.a' or '.lib', then a standard library is created

(typically '/bin/rm'). RM-OPTIONS are options (such as '-f') to be passed
to RM.
If FILE is a libtool library, all the files associated with it are deleted.
Otherwise, only FILE itself is deleted using RM."

Instead it simply concatenates the arguments, separated by ' ', and calls

interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a
special way:
- Space and tab are interpreted as delimiters. They are not treated as
delimiters if they are surrounded by double quotes: "...".
- Unescaped double quotes are removed from the input. Their only effect is
that within double quotes, space and tab are treated like normal
characters.
- Backslashes not followed by double quotes are not special.
- But 2*n+1 backslashes followed by a double quote become
n backslashes followed by a double quote (n >= 0):

## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
