Cubic \((m,n)\)-metacirculant graphs which are not Cayley graphs
Let \(G\) be a cubic \((m, n)\)-metacirculant graph. It is proved that \(G\) is not a Cayley graph if and only if \(G\) is the union of disjoint copies of a generalized Petersen graph \(P(d, k)\) with \(d> 2\) and \(k^2\equiv -1\pmod d\).
