Graphs Related to Classical Geometries,aphs are distance-regular. In the last three sections we construct several infinite families of antipodal covers of complete graphs (starting from affine instead of projective points), and an infinite family of partial geometries yielding bipartite distance-regular graphs of diameter 4 (starting from complete arcs in a projective plane).

W. E. Staas Jr.,H. M. Cioschi,B. Jacobs partition of . into cosets of ., we take an arbitrary partition Π of Γ, Now there is an obvious concept of quotient graph Γ / Π generalizing that of coset graph, and Theorem 11.1.6 gives a sufficient condition for this quotient graph to be distance-regular. Section 11.1 is the outgrowth of earlier discussions with A.R. Calderbank.
