Editing GAP (computer algebra system) (section)

==Distribution==
GAP and its sources, including packages (sets of user contributed programs), data library (including a [[list of small groups]]) and the manual, are distributed freely, subject to "[[copyleft]]" conditions. GAP runs on any [[Unix]] system, under [[Microsoft Windows|Windows]], and on [[Apple Macintosh|Macintosh]] systems. The standard distribution requires about 300 MB (about 400 MB if all the packages are loaded).

The user contributed packages are an important feature of the system, adding a great deal of functionality. GAP offers package authors the opportunity to submit these packages for a process of [[peer review]], hopefully improving the quality of the final packages, and providing recognition akin to an academic publication for their authors. {{As of|2021|03}}, there are 151 packages distributed with GAP, of which approximately 71 have been through this process.

An interface is available for using the [[Singular (software)|SINGULAR]] computer algebra system from within GAP.  GAP is also included in the mathematical software system [[SageMath]].
