sage-combinat is a collection of experimental patches #link#
(i.e. extensions) on top of sage, developed by
a community in algebraic combinatorics. Its main purpose is to improve
sage as an extensible toolbox for computer exploration, and foster
code sharing between researchers in this area. The intent is that most
of those patches eventually will get integrated into sage as soon as
they are mature enough, with a typical short life-cycle of a few
weeks.		 Sage-Combinat is a software project whose mission is: '''to improve the open source mathematical system [[http://www.sagemath.org/|Sage]] as an extensible toolbox for computer exploration in (algebraic) combinatorics, and foster code sharing between researchers in this area'''.

 * 2008-06-19: MuPAD-Combinat join forces with Sage

    Sage-combinat was born as a partial port of [[http://mupad-combinat.sf.net|MuPAD-Combinat]]. 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.

Sage-Combinat

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 experimental patches (i.e. extensions) on top of Sage, developed by a community of researchers. The intent is that most of those patches 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.
