Thanks Nicolas!

I'm also stuck in limbo with sage at the moment as I foolishly upgraded to macosx lion, so I'm still using 4.7.1 as I can't compile from source. I am looking forward to the release of sage 5.0:) I am right in thinking that run_snake or it is runsnake?) is available from 4.7.2 onwards? > Does this start to be acceptable? It looks like it is now faster than gap. I'll have to wait until I play with it properly in sage 5 to see how it behaves for larger tableaux. > > This was actually the first step in the calculations that I wanted to > > do, which involved taking certain sums of these idempotents reducing > > the coefficients modulo an ideal and seeing what happened to them.
