Are you sure? Could you give an example? Let b: S -> E o C take a permutation of U and produce the cycle decomposition of the permutation. If s is a relabeling, i.e., a permutation of U, b(s) should produce the corresponding relabeling on E o C [U]. I'd have thought that S and E o C are naturally isomorphic ?
