Let D be a Menon difference set in a group G with parameters (4u2, 2~' -u, u\* -u) and T a divisible difference set (DDS) with parameters (m. n, k, A,, A,) in a group H re
## 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
