Abstract

Quasi-symmetric 2-designs with block intersection numbers 0 and y≥ 2 are studied using an additional property that any triple of points is contained in 0 or p blocks for some positive constant p. Some characterization results including the extremal cases k = y2 + y, λ = y2 + y - 1 and λ = y2 are given. The paper also contains some structural investigations of biplanes of characteristic three.
