I don't entirely agree with Vincent's fix as it hides the symptom of the underlying problem: the quotient is not in finite fields: sage: R. = PolynomialRing(GF(3)) sage: f = x^2 + x + 2 sage: K. = f.root_field() sage: K.category() Category of commutative no zero divisors quotients of algebras ove

2017-10-26 Thread 'B. L.' via sage-devel
Dear Sage-Developers, I came across the following issue / feature request when working with the coding theory classes: Getting a syndrome table of a code over GF(9) works, but using a 'hand-crafted version' of GF(9) will not work, although(?) the available decoders include 'Syndrome'. See the S
