Maximal cliques in the graph of $5$-ary simplex codes of dimension two

Combinatorics 2024-02-09 v1

Abstract

We consider the induced subgraph of the corresponding Grassmann graph formed by qq-ary simplex codes of dimension 22, q5q\ge 5. This graph contains precisely two types of maximal cliques. If q=5q=5, then for any two maximal cliques of the same type there is a monomial linear automorphism transferring one of them to the other. Examples concerning the cases q=7,11q=7,11 finish the note.
