GAP package CrystCat

The crystallographic groups catalog

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.
