I'm not sure if this helps but you could try sage: R.<x0,x1,x2,x3,x4,x5>=PolynomialRing(GF(2),6) sage: f=(1+x1*x2)*x0+x4*x5 sage: print f.coefficient(x0) x1*x2 + 1 or sage: R1.<x1,x2,x3,x4,x5>=BooleanPolynomialRing(5) sage: R2.<x0>=PolynomialRing(R1, 1, "x0") sage: f=(1+x1*x2)*x0+x4*x5 sage: print f.monomial_coefficient(x0) x1*x2 + 1 > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-support+unsubscr...@googlegroups.com. > To post to this group, send email to sage-support@googlegroups.com. > Visit this group at http://groups.google.com/group/sage-support?hl=en. > For more options, visit https://groups.google.com/groups/opt_out. > > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
