On (a, b)-consecutive petersen graphs

The generalized Petersen graphsP(n,k), n≥3, 1≤k<n/2, consist of an outern-cyclexox1x2...xn−1, a set ofn spokesxiyi (0≤i≤n−1), andn inner edgesyiyi+k with indices taken modulon. This paper deals with (a,b)-consecutive labelings of generalized Petersen graphP(n,k).
