GAP (Groups, Algorithms and Programming) is a system for computational discrete algebra with particular emphasis on, but not restricted to computational group theory. Basic Functionality includes long integer and rational arithmetic, cyclotomic fields, finite fields, residue class rings (GAP 4), p-adic numbers (GAP 4), polynomials (multivariate polynomials and rational functions in GAP 4), vectors and matrices, various combinatorial functions, elementary number theory, a wide variety of list operations.

Groups can be given in various forms: for example as permutation or matrix groups (by generating elements), as finitely presented groups or as polycyclicly presented groups. GAP knows how to construct a number of well-known groups such as symmetric and classical groups. There is a wide variety of functions for the investigation of groups being able to compute; e.g. size, conjugacy classes of elements, derived series, composition series (including identification of the composition factors), Sylow subgroups, certain characteristic subgroups, maximal subgroups, normal subgroups, subgroup lattice, automorphism group, cohomology groups and character table.

Ordinary representations (over fields of characteristic 0) are mainly investigated via their characters. GAP provides methods to compute character tables automatically from concretely given groups (e.g. permutation groups) as well as a large set of tools for calculating with (partial) characters for the interactive construction of character tables.
