Abstract

Four circulant (or type 1) (0,1,−1) matrices X1, X2, X3, X4 of order t with the property that each of the t2 positions is non-zero in precisely one of the Xi and such that

$$X_1 X_1 ^T + X_2 X_2 ^T + X_3 X_3 ^T + X_4 X_4 ^T = tI_t$$

will be called T-matrices.

This paper studies the construction, use and properties of T-matrices giving a new construction for Hadamard matrices and some new equivalence results for Hadamard matrices and Baumert-Hall arrays.

Written while this author was visiting the Mathematics Department, S.U.N.Y. at Buffalo, New York.
