WebMay 18, 2013 · It is a theorem, the Hoffman-Singleton theorem, that any graph satisfying those three properties must have either degree 2, 3, 7 or 57. In the first three cases, existence and uniqueness have been confirmed (with the pentagon, Petersen graph and Hoffman-Singleton graph, respectively). As for degree 57, it is unknown whether such … WebHoffman-Singleton graph. There is a unique strongly regular graph Γ with parameters v = 50, k = 7, λ = 0, μ = 1. The spectrum is 7 1 2 28 (–3) 21 . It was found by Hoffman & … WebProperties of the Hoffman-Singleton graph If we consider a specified vertex in a graph with order n, degree d, and diameter k, and let ni be the number of vertices at a distance of i edges from that vertex, then the following inequality (from Moore, used by Hoffman and Singleton [7], and Miller and Siran [11]) holds: ni ≤ d(d – 1)i - 1 (1) binary logistic regression là gì
