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
The enumeration of transitive ordered factorizations of a given permutation is a combinatorial problem related to singularity theory. Let n β₯ 1, and let Ο 0 be a permutation of n having d i cycles of length i, for i β₯ 1. Let m β₯ 2. We prove that the number of m-tuples Ο 1 Ο m of permutations of n su
