GAP is a system for computational discrete algebra, with particular emphasis
on Computational Group Theory. GAP provides a programming language, a library
of thousands of functions implementing algebraic algorithms written in the GAP
language as well as large data libraries of algebraic objects. GAP is used in
research and teaching for studying groups and their representations, rings,
vector spaces, algebras, combinatorial structures, and more.

This package provides a catalog of crystallographic groups of dimensions 2,
3, and 4 which covers most of the data contained in the book Crystallographic
groups of four-dimensional space by H. Brown, R. Bülow, J. Neubüser, H.
Wondratschek, and H. Zassenhaus (John Wiley, New York, 1978). Methods for the
computation with these groups are provided by the package Cryst, which must
be installed as well.
This package was written by Volkmar Felsch and Franz Gähler.
