... Hemisystems were introduced by Segre [640], who showed that a nontrivial h-spread of U(4,q) must be a hemisystem, and constructed such hemisystems in case q ...

Abstract In this paper we unify several existing regularity conditions for graphs, including strong regularity, k-isoregularity, and the t-vertex condition.
