Comment (by dimpase):
my problem with this patch that it uses `is_prime` instead of
`is_prime_power` to build Paley matrices. While the present implementation
of Paley matrices needs primes, it's entirely unnecessary. Should I add a
patch that fixes this here?
(or else, surely it's not a big deal to process errors from Paley
constructions here rather than limit their inputs...)
