You can try sage: x= polygen(GF(2), a) and try a few expressions involving x. For example sage: 2*x 0 since 2=0 in GF(2). Pierre On Tuesday, March 11, 2014 3:25:04 PM UTC+1, Prakash Dey wrote: I am new to sage. x=var('a') print x*x*x*x+x*x*x+x*x+x How to do this symbolic algebra in

You could work in the polynomial ring generated by the ak, modulo the relation ak**2 = ak: P=PolynomialRing(GF(2),[a%d % i for i in (0,..,5)]) I=P.ideal([u*u-u for u in P.gens()]) Q=P.quotient(I) @cached_function def z(k): if k 6: return Q.gens()[k] return z(k-6)+z(k-3)+z(k-2)*z(k-1)
