For a graph G, let 9(G) be the family of strong orientations of G, d(G) = min{d(D) / D t 9' (G)} and p(G) = d(G) -d(G), where d(G) and d(D) are the diameters of G and D respectively. In this paper we show that p(G) = 0 if G is a Cartesian product of (I ) paths, and (2) paths and cycles, which satis

β¦ Synopsis
Let G x H denote the Kronecker product of graphs G and H. Principal results are as follows: (a) If m is even and n-0 (mod 4), then one component of P,.+l x P,+1, and each component of each of CA x Pn+l, Pm+l x (7, and Cm x C, are edge decomposable into cycles of uniform length rs, where r and s are suitable divisors of m and n, respectively, (b) if m and n are both even, then each component of each of Cm X P,+I, P,.+l X C, and C,. Γ C. is edge-decomposable into cycles of uniform length ms, where s is a suitable divisor of n, (c) C2i+1 Γ C2j+l is factorizable into shortest odd cycles, (d) each component C4i x C4j is factorizable into four-cycles, and (e) each component of Cmx C4j admits of a bi-pancyclic ordering.

## Abstract In the study of decompositions of graphs into paths and cycles, the following questions have arisen: Is it true that every graph __G__ has a smallest path (resp. pathβcycle) decomposition __P__ such that every odd vertex of __G__ is the endpoint of exactly one path of __P__? This note g
## Abstract Bondy conjectured that every simple bridgeless graph has a small cycle double cover (SCDC). We show that this is the case for the lexicographic products of certain graphs and along the way for the Cartesian product as well. Specifically, if __G__ does not have an isolated vertex then __
