GAP 3 Share Package "grim"

GRIM: Groups of Rational and Integer Matrices

Share package since release 3.4, about April 1997, communicated by Akos Seress, Columbus, OH 43210.
This package has not been transferred to or replaced in GAP 4, but some of its functionality, e. g. determining whether an integral matrix group is finite, is available (by a different algorithm) as a method for 'IsFinite' in GAP 4.
