poly = 7 + x + 4 y + 4 x y + 3 z + 2 x z + 4 y z + 4 x y z;
PolynomialMod[poly, 2]
x+z+1

Howdy,
How does one reduce a polynomial's coefficients modulo 2? For
example, I have a function that sums several polynomials, and
currently produces a result like this:
7 + x + 4 y + 4 x y + 3 z + 2 x z + 4 y z + 4 x y z
I want to reduce this to
1 + x + z
I thought I might be able to do this by somehow coercing the terms
into a list and then doing Sum[L[[i]],{i,1,Length[L]},Modulus->2], but
no such luck.
Any ideas?
Thanks,
Bob H
