Editing GAP (computer algebra system) (section)

==Features==
GAP contains a [[Procedural programming|procedural programming language]] and a large collection of functions to create and manipulate various mathematical objects. It supports integers and rational numbers of arbitrary size, memory permitting. [[Finite group|Finite groups]] can be defined as [[Permutation group|groups of permutations]] and it is also possible to define [[Finitely-presented group|finitely presented groups]] by specifying generators and relations.  Several databases of important finite groups are included. GAP also allows to work with [[Matrix (mathematics)|matrices]] and with [[Finite field|finite fields]] (which are represented using [[Conway polynomial (finite fields)|Conway polynomials]]). [[Ring (mathematics)|Rings]], [[Module (mathematics)|modules]] and [[Lie algebra|Lie algebras]] are also supported.
