Title
Regular embeddings of Kn,n where n is a power of 2. II: The non-metacyclic case
Abstract
The aim of this paper is to complete a classification of regular orientable embeddings of complete bipartite graphs K"n","n, where n=2^e. The method involves groups G which factorise as a product G=XY of two cyclic groups of order n such that the two cyclic factors are transposed by an involutory automorphism. In particular, we give a classification of such groups G in the case where G is not metacyclic. We prove that for each n=2^e, e=3, there are up to map isomorphism exactly four regular embeddings of K"n","n such that the automorphism group G preserving the surface orientation and the bi-partition of vertices is a non-metacyclic group, and that there is one such embedding when n=4.
