Let G be a non-bipartite strongly regular graph on n vertices of valency k. We prove that if G has a distance-regular antipodal cover of diameter 4, then k β€ 2(n + 1)/5 , unless G is the complement of triangular graph T (7), the folded Johnson graph J (8, 4) or the folded halved 8-cube. However, for

Let [' be a distance regular graph with intersection array {bo, bl, . β’., bd\_l; ct, ..., ed}. It is shown that in same cases (c i 1, ai-I, br I) = (ct, at, bt) and (c2~ t, a2~ 1, b2i l) = (ci, a~, bi) imply k <\_ 2b i + 1. As a corollary all distance regular graphs of diameter d = 3i -1 with b I =
Bannai and Ito conjectured in a 1987 paper that there are finitely many distance-regular graphs with fixed degree that is greater than two. In a series of papers they showed that their conjecture held for distance-regular graphs with degrees 3 or 4. In this paper we prove that the Bannai-Ito conject
If G is a regular tripartite graph of degree d(G) with tripartition (A,B,C) of V(G) such that the bipartite subgraphs induced by each ofA UB, BU C, CUA are all regular of degree Β½d(G), then we call G 3-way regular. We give necessary and sufficient conditions for a 3-way regular tripartite graph of d
