Abstract: Let G be a finite group and X a (di)graph. If there exists a semiregular subgroup G¯ of the automorphism group Aut(X) isomorphic to G with n orbits on V(X) then the (di)graph X is called an n-Cayley graph on G. If, in addition, this subgroup G¯ is normal in Aut(X) then X is called a normal n-Cayley graph on G.
