Abstract

If G and H are vertex-transitive graphs, then the framing number fr(G, H) of G and H is defined as the minimum order of a graph every vertex of which belongs to an induced G and an induced H. This paper investigates fr(C_m, C_n) for m < n. We show first that fr(C_m, C_n) ≥ n + 2 and determine when equality occurs. Thereafter we establish general lower and upper bounds which show that fr(C_m, C_n) is approximately the minimum of n - m + 2√n and n + n/m.
