Thank you all for your replies! Now I have another problem: sage: for f in list(GF(2)['x'].polynomials(of_degree=2)): ....: print len(prime_divisors(f)), f ....: 1 x^2 1 x^2 + 1 2 x^2 + x 1 x^2 + x + 1
Only one of these polynomials should have a 1 in the first column (the polynomial that's irreducible). What am I doing wrong?
