GAP Packages
[Accepted packages]
[Deposited 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 succesfully 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 recommented 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.
