In this paper, we will study enumeration of hypergraphs. Let S p be a symmetric group acting on a p-setX . It induces the permutation group S \* p acting on the set of all subsets of X . Our problem is reduced to finding a good formula for the cycle index of S \* p . A crucial point is to calculate
