Comment:
> On my machine, the longest ''single'' test takes about 90 seconds. Since
the documentation of {{{pGroupCohomology.__init__}}} contains many
examples (it is an introduction how to use the package), it is no surprise
that it takes longer, but it is still {{{pGroupCohomology passes in 242.05
s}}}.
{{{
pGroupCohomology passes in 1205.79 s
}}}
So less than six times slower - not bad ;)
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!
Anyway, I can't review this any more because I don't use Singular or GAP
much at all (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), but I will at least add myself as a first
reviewer.
