# Discriminants of $\mathop{\mathfrak{S}}\nolimits_n$-orders

Abstract : Let alpha be an algebraic integer of degree n >= 2. Let alpha(1),..., alpha(n) be the n complex conjugate of alpha. Assume that the Galois group Gal(Q(alpha(1),..., alpha(n))/Q) is isomorphic to the symmetric group S-n. We give a Z-basis and the discriminant of the order Z[alpha(1),..., alpha(n)]. We end up with an open question showing that this problem seems much harder when we assume that Q(alpha)/Q is already Galois or even cyclic.
