Comment:
Dear John,
I am sorry for being late, but I have one question: Would you allow one
last-minute change?
Namely, with the package you just reviewed, the computation of the
cohomology ring of the Sylow 2-subgroup of some double cover of Suzuki
group 8 (this is group number 836 of order 128), the completion test à la
Peter Symonds is very time consuming - the problem was in the computation
of a small subset of generators over which the ring is finite-dimensional.
I found a way to speed it up. Also, I'd like to add protocol output to the
method that computes it (which also means I will have to change the
expected protocol output in some doc tests).
I think these changes are minor, but helpful. If you say that you would
try to install it and run the test suite again, then I would update the
spkg a bit later. I would also accept to postpone that change for a later
spkg version.
What do you prefer?
