Aclib -- A Library of 3- and 4-Dimensional Almost Crystallographic Groups
=========================================================================
AClib -- A Library of 3- and 4-Dimensional Almost Crystallographic Groups
========================================================================

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 AClib package 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
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.
