Hey all, There is a hashing error likely with multivariate Laurent polynomial rings:
sage: R.<a,b> = LaurentPolynomialRing(ZZ) sage: elt = (a + b) * (~a + ~b) - a*~b - ~a*b - 1 sage: elt == R.one() True sage: hash(elt) == hash(R.one()) False This is now http://trac.sagemath.org/ticket/20490. I would appreciate if anyone could figure out what is going wrong with this. Thanks, Travis -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
