In mathematics a Galois Field is a field having a finite number of elements.
Galois fields are one of two types:
- The integers modulo a prime number p, represented by Zp
- The polynomials with coefficients modulo a prime number p having operations modulo with an irreducible n-degree polynomial r(x), represented by Fp^n
A Galois field with q=p^n elements is typically denoted by GFq or Fq.
