A Class of Strongly Regular Graphs Related to Orthogonal Groups
1983Publisher Summary This chapter describes a class of regular graphs related to PO 2n+l (q). If q is odd, the vertices of the graphs may be seen as a set of points off a quadric in PG(2n,q). It has been noticed that regular graphs of the same kind occur in symplectic spaces over GF(2 r ). The chapter presents a unified description of those graphs for a

On a strongly regular relation in hypergroupoids
1993Let \(H\) be a hypergroupoid and \(n \in \mathbb{N}^*\). Let \(\gamma\) be a grouping of the indices \(\{1,\dots,n\}\) respecting their order. If \(z_ 1,z_ 2,\dots,z_ n\) are elements of \(H\) we denote by \(\displaystyle\prod^ n_{i=1}{^{(\gamma)} z_ i}\) the product of these elements according to \(\gamma\). Define on \(H\) a relation \(\Delta\) by: \(

Block designs and strongly regular graphs related to the group U(3, 4)
2005We show a construction of a two block designs, 2-(65, 15, 21) design and 2-(65, 26, 250) design, Steiner system S(2, 5, 65) and its block graph, two strongly regular graphs (208, 75, 30, 25) and (416, 100, 36, 20) and binary code of length 65 from the unitary group U(3, 4). Those incidence structures are defined on the elements of the conjugacy classes
