Quasi‐Hermitian varieties V inPG ( r , q 2 ) are combinatorial generalizations of the (nondegenerate) Hermitian variety H ( r , q 2 ) so that V and H ( r , q 2 ) have the same size and the same intersection numbers with hyperplanes. In this paper, we construct a new family of quasi‐Hermitian varieties. The isomorphism problem for the associated strongly regular graphs is discussed for r = 2 .
