Abstract:
An S-ring (a Schur ring) is said to be separable with respect to a class of groups K if every its algebraic isomorphism to an S-ring over a group from K is induced by a combinatorial isomorphism. It is proved that every Schur ring over an Abelian group G of order 4p, where p is a prime, is separable with respect to the class of Abelian groups. This implies that the Weisfeiler-Lehman dimension of the class of Cayley graphs over G is at most 3.
