Let K be a finite abelian group and let exp(K) denote the least common multiple of the orders of the elements of K. A BH(K, h) matrix is a K-invariant |K|×|K| matrix H whose entries are complex hth roots of unity such that HH∗ = |K|I, where H∗ denotes the complex conjugate transpose of H, and I is t...
