Abstract: Let be the symmetric group on the symbols . We show that the center of the group-ring coincides with the set of symmetric polynomials with integral coefficients in the elements , where is a sum of transpositions, . In particular, every conjugacy-class-sum of is a symmetric polynomial in .
