#5353: add xgcd for polynomial over GF(2)
---------------------------------+------------------------------------------
Reporter: mhansen | Owner: malb
Type: defect | Status: new
Priority: minor | Milestone: sage-3.4.1
Component: commutative algebra | Keywords:
---------------------------------+------------------------------------------
Currently, this fails:
{{{
sage: R.<x> = GF(2)[]
sage: fr = ((x+1)/(x^3+x+1) + (x+1)/(x^3+x^2+1));
sage: fr.partial_fraction_decomposition()
