Below you can download the zipped tar archives of the released packages of the homalg project. The unreleased packages are not listed here.

Here you can find the Git repositories (cgitgitweb) of some released and unreleased packages. They are only meant for developers. (You can find our quick tutorial to Git here). You can also follow most of the packages on github. Before you send us pull requests please have a look at the online book Pro Git.

Due to the high interdependency between the different packages, their coherence has to be guaranteed. The list below should provide compatible versions. If not please contact us.

The first item of the list below is a zipped tar archive containing as subdirectories all the released packages in compatible versions.

Please be sure not to violate the compatibility when you update single packages. Don't forget to rebuild GAP4's preloaded workspace in case it includes some of the packages you want to update!

The tar archives should be extracted inside the GAP4-subdirectory pkg.
