On maximal cliques of Cayley graphs over fields

Combinatorics 2022-08-16 v2

Abstract

We describe a new class of maximal cliques, with a vector space structure, of Cayley graphs defined on the additive group of a field. In particular, we show that in the cubic Paley graph with order q3q^3, the subfield with qq elements forms a maximal clique. Similar statements also hold for quadruple Paley graphs and Peisert graphs with quartic order.
