In practice, Sage-combinat is a collection of branches on top of Sage , developed by a community of researchers. The intent is that most of those branches get eventually integrated into Sage as soon as they are mature enough, with a typical short life-cycle of a few weeks. In other words: just install Sage, and you will benefit from all the Sage-combinat development, except for the latest bleeding edge features.

After months of discussions and experiments, an enthusiastic consensus emerged in the MuPAD-Combinat community to join Sage. Sage-combinat henceforth became the natural successor of MuPAD-Combinat . The transition was a massive investment (and is not yet completely over): seven years of hard work to port over! However a lot of experience was gained since 2000, and most of the design was pretty clear, and we could *share* the work. Who are we? What is Sage-Combinat used for?

Code Since Sage 6.0, the development workflow has been reworked in depth, and we are in the progress of migrating the extensions as git branches. Here are some useful links: Closed tickets related to combinatorics In-progress tickets related to combinatorics Some conventions and help with the new git The Sage-Combinat extensions used to be managed as a collection of patches on our patch server , using a so-called mercurial queue. Quite some stuff below is thus outdated, and will be progressively replaced by information on the new workflow. Browse the Sage sources with the Sage-combinat patches applied (only useful for Sage version prior to sage-6.0) Developing for Sage-Combinat on Windows: Sage Development on Windows .
