Given an odd prime p we show a way to construct large families of polynomials P q (x) E Q[x], q ∈ C, where C is a set of primes of the form q ≡ 1 mod p and P q (x) is the irreducible polynomial of the Gaussian periods of degree p in Q(ζ q ). Examples of these families when p = 7 are worked in detail. We also show, given an integer n > 2 and a prime q ≡ 1 mod 2n, how to represent by matrices the Gaussian periods η 0 ,...,η n of degree n in Q(ζ q ), and how to calculate in a simple way, with the help of a computer, irreducible polynomials for elements of Q(η 0 ).
