      GAP Packages

      Since 1992, sets of user contributed programs, called packages, have been distributed with GAP. For convenience of the GAP users, the GAP Group redistributes packages, but the package authors remain responsible for their maintenance.

      There is a designated and documented mechanism for loading packages into GAP including a smooth integration of the documentation into the GAP help system. (See this page for hints how to write your own package and the reference manual chapter about installing and loading packages.)

      Some packages represent a piece of work equivalent to a sizeable mathematical publication. To acknowledge such work there has been a refereeing process for packages since 1996. See Submitting Contributions to GAP for more information on this. We call a package an accepted package (with GAP 3 the term share packages was used) when it was successfully refereed or already distributed with GAP before the refereeing process was started. All other packages distributed here and not in this category are called deposited packages, these may be submitted for refereeing or the authors may not want to submit them for various reasons.

      This page lists current versions of GAP packages redistributed with GAP, and the page Manuals informs about presently available package manuals.

      If you are interested to find GAP packages hosted on GitHub or BitBucket, please see this page.

      If you are familiar with the previous GAP distributions, note that now we do not distribute a merged archive of all currently redistributed packages. All these packages are now included in the same archive with the core GAP system, adding a significant amount of functionality. Dependencies between packages are illustrated by the following graph. Each package is also available in a single archive which may be used e.g. for a later upgrading, though the recommended way to upgrade the system is just to reinstall it as explained on the upgrade page.

      Also see Data Libraries, Deposited Contributions, and Undeposited Implementations.

      Accepted Packages

      Here is the current list of accepted packages. They are either redistributed by the GAP Group since before the refereeing process was setup, or they have been successfully refereed. The packages are sorted alphabetically, except for some data library packages, given in a separate list.

      Follow the links to find brief descriptions of each package, as well as further information including download and installation instructions.

      No longer redistributed with GAP or renamed:

      • Carat - this package has been renamed to CaratInterface.
      • Citrus - this package has been renamed to Semigroups.
      • Convex - this package has been superseded by NConvex.
      • Gpd - this package has been renamed to groupoids.
      • HAPprime - part of the code has been incorporated into the HAP package. Its source code repository, containing the code of the last distributed version, can still be found on GitHub here.
      • if - this package has been withdrawn; a better functionality is now included in the newer package SCSCP.
      • LAG - the functionality of this package is now included in the newer package LAGUNA.
      • linboxing - this package has been unusable (it does not compile) for several years preceding GAP 4.10 release, and is unmaintained. It was therefore dropped from the GAP package distribution. If anybody is willing to take over and fix the package, the latest sources are available here.
      • MONOID - the functionality of this package is now included in the newer package Semigroups.
      • NQL - this package has been withdrawn by the author, and later has been superseded by the package lpres.
      • ParGAP is no longer redistributed with GAP because it no longer can be compiled with GAP 4.9 (see this announcement). Its source code repository, containing the code of the last distributed version, plus some first fixes needed for compatibility for GAP 4.9, can still be found on GitHub here. If somebody is interested in repairing this package and taking over its maintenance, so that it can be distributed again, please contact the GAP team.
      • PolymakeInterface - this package has been withdrawn.
      • QaoS is no longer redistributed with GAP because the servers it crucially relies on for its functionality have been permanently retired (see this announcement). Its source code repository, containing the code of the last distributed version, can still be found on GitHub here. If somebody is interested in repairing this package and taking over its maintenance, so that it can be distributed again, please contact the GAP team.
      • recogbase - this package has been merged into the recog package, and therefore is no longer distributed with GAP.
