The issue is that you redefined x after defining K. I wrote more on the ticket. David On Fri, Nov 22, 2019 at 1:57 AM Dima Pasechnik wrote: > This is a variable name clash. Somehow, using 'x' for modulus creates a > problem. > If I instead do > > T.=GF(2)[] > K.=GF(2^6, modulus=xx^6 + xx^4 + xx

This is a variable name clash. Somehow, using 'x' for modulus creates a problem. If I instead do T.=GF(2)[] K.=GF(2^6, modulus=xx^6 + xx^4 + xx^3 + xx + 1) ... then everything works as expected. On Fri, Nov 22, 2019 at 9:51 AM Dima Pasechnik wrote: > > This is now https://trac.sagemath.org/tic
