Cliqueful graphs as a means of calculating the maximal number of maximum cliques of simple graphs

Abstract

A simple graph on nn vertices may contain a lot of maximum cliques. But how many can it potentially contain? We will show that the maximum number of maximum cliques is taken over so-called cliqueful graphs, more specifically, later we will show that it is taken over saturated composite cliqueful graphs, if n15n \ge 15. Using this we will show that the graph that contains 3n/3c3^{\lfloor n/3 \rfloor}c maxcliques has the most number of maxcliques on nn vertices, where c{1,43,2}c\in\{1,\frac{4}{3},2\}, depending on n mod 3n \text{ mod } 3.
