Let [' be a distance regular graph with intersection array {bo, bl, . •., 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 =
