✦ Synopsis

Let A = B G , where B is a Noetherian algebra over a field K of characteristic p = 0 and G is a finite group such that p divides |G|. We give estimates for the depth of A in terms of the codimension of the branch locus of the extension B/A.

It is a fairly longstanding conjecture that if G is any finite group with IG/ > 2 and if X is any set of generators of G then the Cayley graph T(G : X) should have a Hamiltonian cycle. We present experimental results found by computer calculation that support the conjecture. It turns out that in the
