Using lines and half lines in a two-dimensional vector space over G F(q), we generalize the constructions of difference families of Xia and Liu which are important for the construction of Williamson-type matrices. Also based on this geometric point of view, we give new and simpler proofs for these c

## Abstract We construct an incidence structure using certain points and lines in finite projective spaces. The structural properties of the associated bipartite incidence graphs are analyzed. These __n__ Γ— __n__ bipartite graphs provide constructions of __C__~6~‐free graphs with Ξ©(__n__^4/3^ edges
