## Abstract We obtain new conditions on the existence of a square matrix whose Gram matrix has a block structure with certain properties, including Dβoptimal designs of order $n\equiv 3 \pmod 4$, and investigate relations to group divisible designs. We also find a matrix with large determinant for

We consider the problem of determining cp(G v KC), the smallest number of cliques required to partition the edge set of the graph G v K~, where G is a finite simple graph and K~, is the empty graph on m vertices. A lower bound on cp(G v K~,,,) is obtained which, when applied to the case G = K,, shar
