Hi!
The mission statement or our project on cohomology rings says that we
should make a data base publically available. It should in some way be
available for Sage (say, as an optional/experimental package), but I
wonder if it is possible.
1) An spkg just with our programs would be about 460 MB.

If you write a polynomial multiplication program that has certain

I recommend to you using the declarative layer

This makes it easier to you, to jump into SA.
Moreover, the declarative extension

Thanks. I have switched to maximal_faces().
I had a simplicial complex, s, and typed "s." + TAB to see the
completions. I saw s.facets, before seeing s.maximal_faces, then was
confused by getting an error from s.facets(). It seems to be a
convention with Sage to keep attributes hidden, so I th

I like the site the way it is. I've been translating many of the pages
into Russian, and the great thing about the design is the simplicity.

I wonder if there could be an online mechanism for suggesting
reviewers. Sometimes I look at a patch, and I think (for example)
"I'm not sure I can review this well, but I bet X or Y could...". I
don't want to "assign" them the ticket, since that seems overbearing.

I put the relevant usernames in the cc: box, presuming that they might
