Let G [XI H be the strong product of graphs G and H. We give a short proof that Kneser graphs are then used to demonstrate that this lower bound is sharp. We also prove that for every n > 2 there is an infinite sequence of pairs of graphs G and G' such that G' is not a retract of G while G' IXI K,

## Abstract We prove that the strong product of any at least ${({\rm ln}}\, {2})\Delta+{O}(\sqrt{\Delta})$ nonβtrivial connected graphs of maximum degree at most Ξ is pancyclic. The obtained result is asymptotically best possible since the strong product of β(lnβ2)__D__β stars __K__~1,__D__~ is not
We prove that the strong product G 1 G 2 of G 1 and G 2 is Z 3 -flow contractible if and only if G 1 G 2 is not T K 2 , where T is a tree (we call T K 2 a K 4 -tree). It follows that G 1 G 2 admits an NZ 3-flow unless G 1 G 2 is a K 4 -tree. We also give a constructive proof that yields a polynomial
