摘要
With any permutation g of a set Omega is associated a partition of Omega into the cycles of g. What information do we get about a group G of permutations if we know either the set or the multiset of partitions of Omega, or of partitions of n = vertical bar Omega vertical bar, which arise as the cycle partitions of its elements? Some partial answers to these questions are given. (c) 2004 Elsevier B.V. All rights reserved.
