In the paper we consider some constructions of (k, 6)-graphs that are isomorphic to an induced subgraph of the incidence graph of a finite projective plane, and present some unifying concepts.Also, we obtain new bounds on and exact values of Zarankiewicz numbers, mainly when the parameters are close to those of a design.
