Sažetak
In this paper we study the 2-Y-homogeneous condition of the incidence graphs of2-designs. We prove that quasi-symmetric 2-designs which can be obtained by the famous Cameron’s extension theorem, i.e., those which are quasi-symmetric 3-designs with intersection numbers 0 and y=lambda+1, are the only 2-designs which have 2-Y-homogeneous distance-biregular incidence graphs. Moreover, we prove that every 2-Y-homogeneous distance-biregular graph with eccentricity D=3 must be the incidence graph of such a design.
