Comment (by jsrn):
Noticed the following: In one place, you should be computing `sigma^t(g)`
for some power `t` and some element `g`, where `sigma` is the Frobenius
automorphism. You implement this as `pow(sigma(g), t)`, but that's not
what it means. Rather, it means `sigma( sigma( ... sigma(g)...)`, where
there is `t` sigmas. In another place, you compute simply `g^(q^t)`
instead of calling `sigma`, which is also bad style; it should again be
`sigma` called `t` times on `g`.
