*GAP package for finding isomorphism classes of finite groups*

**Branch:** pkgsrc-2009Q1,

**Version: **2.0nb1,

**Package name:** gp-grpconst-2.0nb1,

**Maintainer: **cjepGrpConst is a GAP 4 package for constructing all groups of a given

finite order (up to isomorphism).

FrattiniExtensionMethod constructs all soluble groups of a given

order.

CyclicSplitExtensionMethod constructs all (necessarily soluble) groups

whose given orders are of the form pn .q for different primes p and q

and which have at least one normal Sylow subgroup.

UpwardsExtensions takes as its input a permutation group G and

positive integer s and returns a list of permutation groups, one for

each extension of G by a soluble group of order a divisor of s.

The programs in this package have been used to construct a large part

of the Small Groups library.
