"The AClib package contains a library of almost crystallographic groups and a some algorithms to compute with these groups. A group is called almost crystallographic if it is finitely generated nilpotent-by-finite and has no non-trivial finite normal subgroups. Further, an almost crystallographic group is called almost Bieberbach if it is torsion-free. The almost crystallographic groups of Hirsch length 3 and a part of the almost cyrstallographic groups of Hirsch length 4 have been classified by Dekimpe. This classification includes all almost Bieberbach groups of Hirsch lengths 3 or 4. The AClib package gives access to this classification; that is, the package contains this library of groups in a computationally useful form. The groups in this library are available in two different representations. First, each of the groups of Hirsch length 3 or 4 has a rational matrix representation of dimension 4 or 5, respectively, and such representations are available in this package. Secondly, all the groups in this libraray are (infinite) polycyclic groups and the package also incorporates polycyclic presentations for them. The polycyclic presentations can be used to compute with the given groups using the methods of the Polycyclic package.",

consist of either the Standard Version, or a Modified Version.
"Distribute" means providing a copy of the Package or making it accessible to
anyone else, or in the case of a company or organization, to others outside of
your company or organization.
"Distributor Fee" means any fee that you charge for Distributing this Package or
providing support for this Package to another party. It does not mean licensing
fees.
"Standard Version" refers to the Package if it has not been modified, or has
been modified only in ways explicitly requested by the Copyright Holder.
"Modified Version" means the Package, if it has been changed, and such changes
were not explicitly requested by the Copyright Holder.
"Original License" means this Artistic License as Distributed with the Standard
Version of the Package, in its current version or as it may be modified by The
Perl Foundation in the future.
"Source" form means the source code, documentation source, and configuration
files for the Package.
"Compiled" form means the compiled bytecode, object code, binary, or any other
form resulting from mechanical transformation or translation of the Source form.
Permission for Use and Modification Without Distribution (1) You are permitted
to use the Standard Version and create and use Modified Versions for any purpose
without restriction, provided that you do not Distribute the Modified Version.
Permissions for Redistribution of the Standard Version (2) You may Distribute
verbatim copies of the Source form of the Standard Version of this Package in
any medium without restriction, either gratis or for a Distributor Fee, provided
that you duplicate all of the original copyright notices and associated
disclaimers. At your discretion, such verbatim copies may or may not include a
Compiled form of the Package.
(3) You may apply any bug fixes, portability changes, and other modifications
made available from the Copyright Holder. The resulting Package will still be
considered the Standard Version, and as such will be subject to the Original
License.
Distribution of Modified Versions of the Package as Source (4) You may
Distribute your Modified Version as Source (either gratis or for a Distributor
Fee, and with or without a Compiled form of the Modified Version) provided that
you clearly document how it differs from the Standard Version, including, but
not limited to, documenting any non-standard features, executables, or modules,
and provided that you do at least ONE of the following:
(a) make the Modified Version available to the Copyright Holder of the Standard
Version, under the Original License, so that the Copyright Holder may include
your modifications in the Standard Version. (b) ensure that installation of your
Modified Version does not prevent the user installing or running the Standard
Version. In addition, the Modified Version must bear a name that is different
from the name of the Standard Version. (c) allow anyone who receives a copy of
the Modified Version to make the Source form of the Modified Version available
to others under (i) the Original License or (ii) a license that permits the
licensee to freely copy, modify and redistribute the Modified Version using the
same licensing terms that apply to the copy that the licensee received, and
requires that the Source form of the Modified Version, and of any works derived
from it, be made freely available in that license fees are prohibited but
Distributor Fees are allowed.
Distribution of Compiled Forms of the Standard Version or Modified Versions
without the Source (5) You may Distribute Compiled forms of the Standard Version
without the Source, provided that you include complete instructions on how to
get the Source of the Standard Version. Such instructions must be valid at the
time of your distribution. If these instructions, at any time while you are
carrying out such distribution, become invalid, you must provide new
instructions on demand or cease further distribution. If you provide valid
instructions or cease distribution within thirty days after you become aware
that the instructions are invalid, then you do not forfeit any of your rights
under this license.
(6) You may Distribute a Modified Version in Compiled form without the Source,
provided that you comply with Section 4 with respect to the Source of the
Modified Version.
Aggregating or Linking the Package (7) You may aggregate the Package (either the
Standard Version or Modified Version) with other packages and Distribute the
resulting aggregation provided that you do not charge a licensing fee for the
Package. Distributor Fees are permitted, and licensing fees for other components
in the aggregation are permitted. The terms of this license apply to the use and
Distribution of the Standard or Modified Versions as included in the
aggregation.
(8) You are permitted to link Modified and Standard Versions with other works,
to embed the Package in a larger work of your own, or to build stand-alone
binary or bytecode versions of applications that include the Package, and
Distribute the result without restriction, provided the result does not expose a
direct interface to the Package.
Items That are Not Considered Part of a Modified Version (9) Works (including,
but not limited to, modules and scripts) that merely extend or make use of the
Package, do not, by themselves, cause the Package to be a Modified Version. In
addition, such works are not considered parts of the Package itself, and are not
subject to the terms of this license.
General Provisions (10) Any use, modification, and distribution of the Standard
or Modified Versions is governed by this Artistic License. By using, modifying
or distributing the Package, you accept this license. Do not use, modify, or
distribute the Package, if you do not accept this license.
(11) If your Modified Version has been derived from a Modified Version made by
someone other than you, you are nevertheless required to ensure that your
Modified Version complies with the requirements of this license.
(12) This license does not grant you the right to use any trademark, service
mark, tradename, or logo of the Copyright Holder.
(13) This license includes the non-exclusive, worldwide, free-of-charge patent
license to make, have made, use, offer to sell, sell, import and otherwise
transfer the Package with respect to any patent claims licensable by the

=========================================================================
by Karel Dekimpe and Bettina Eick
Introduction
------------
The package `aclib' contains the almost crystallographic groups as
classified by K. Dekimpe in the Springer Lecture Notes, Vol. 1639:
"Almost Bieberbach Groups: Affine and Polynomial Structures".
The groups are available as rational matrix groups. Further, all the
groups in the library are polycyclic. If the `Polycyclic' package for
computations with infinite polycyclic groups is installed, then also
polycyclic presentations for the almost crystallographic groups are
available and can be used for computations with these groups.
