Sage-Combinat: enhancing Sage as a toolbox for computer exploration in algebraic combinatorics

Sage-Combinat is a software project whose mission is: to improve the open source mathematical system Sage as an extensible toolbox for computer exploration in (algebraic) combinatorics, and foster code sharing between researchers in this area.

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.
