Ah, thanks! Fields are a lot less intimidating than I thought they would be! Well, I mean: the basic idea (after reading these replies + wikipedia).

- vmilner 4y agoThere is a finite field (or Galois field GF(p)) of size p for any prime p. This can be exhibited by integers mod p. There are also finite (Galois) fields GF(p^n) of size p^n (positive integer powers of p) These can be exhibited by polynomials with coefficients in the GF(p) field with up to n terms. Eg for p = 2 and n = 3 0 1 x 1 + x 1 + x + x^2 1 + x^2 x + x^2 x^2
