Comment:
I'm having trouble getting the PARI code to work in characteristic 2, but
even in odd characteristic there seem to be some issues:
{{{
pari: T = ffinit(3, 2);
pari: y = ffgen(T, 'y);
pari: hyperellcharpoly(x^3 + y*x)
*** at top-level: hyperellcharpoly(x^3
*** ^--------------------
*** hyperellcharpoly: bug in PARI/GP (Segmentation Fault), please
report.
}}}
Off to go report this upstream...
