Computer Science Computer Science, Theory & Methods Mathematics Mathematics, Applied Physical Sciences Science & Technology Technology
It is well-known that one may construct several strongly regular graphs on the positions of a Latin square, where adjacency corresponds to any subset of the relations on distinct positions of being in the same row, being in the same column, having the same entry, or none of these. We describe the local spectrum and subconstituent (Terwilliger) algebras of such strongly regular graphs.
