Comment (by andrew.mathas):
@darij Sorry, I haven't looked at this (or your query on MO), and I doubt
that I will have time to do this any time soon.
I just tried reading quickly through the latest patch but I didn't see
anything related to how the `mult` variable interacts with the seminormal
form. All I noticed was the unusual choice of reference:) My guess is that
if I looked at this code properly then I'd probably want to rewrite it
from scratch as I seem to remember that the seminormal form code in sage
is far more computationally intensive than it needs to be (working with
the seminormal form is very different from working with the primitive
idempotents whereas last time I looked at this code it confused these two
problems).
If everyone else is happy with the changes then I suggest you just give it
a positive review rather than waiting for me to have time to look at it
properly.
