Pseudo-conway polynomials: https://mail.google.com/mail/u/0/#inbox/1526643c3762b30a

Hi William, I don't think any of us wrote up pseudo-Conway polynomials in particular, since most of the actual algorithms are simple modifications of the ones for Conway polynomials. For details, see sage/rings/finite_rings/conway_polynomials.py especially the docstrings for PseudoConwayLattice, PseudoConwayLattice.polynomial. _frobenius_shift is also needed, but a bit fiddly.
