> I think the timeout was because I had a heavy other load (watching Carl
Witty's video, downloading things) when I ran it the first time. But
remember, this is a 1.25 GHz machine with only 1 GB memory!
OK, my machine has 2 GB. But actually keeping the memory consumption low
was a driving force behind many things that I did for the first version of
the package. As a result, the cohomology for most (but not all) groups of
order 128 can be computed with 2 GB.
But I think I should put "find smaller test cases" on my to-do list for
version 2.2.

much at all
What a pity! But thanks for your effort!
> (though I still think it's cool that you are calculating the cohomology
rings as rings, there has to be a way to apply this nicely to the topology
stuff in Sage),
I wonder if this will be possible. As it is, the package is very much
addressed to algebra, and I don't see how this could be changed.

Sure!
Best regards,
Simon
