Cliques in Paley graphs of square order and in Peisert graphs
Andries E. Brouwer, Sergey Goryainov, Leonid Shalaginov +1
We study maximal cliques in the collinearity graphs of Desarguesian nets, give some structural results and some numerical information. In particular, we show for Desarguesian nets…

A construction of directed strongly regular graphs with parameters (63,11,8,1,2)
Andries E. Brouwer, Dean CrnkoviÄ, Andrea Å vob
In this paper, we prove the existence of directed strongly regular graphs with parameters . We construct a pair of nonisomorphic dsrg(63,11,8,1,2), where one is obta…
