116×116 {-1, +1} matrices of maximal determinant

Ratio of |Det R_j| to Hadamard bound: 1

M=R_j^TR_j= R_j R_j^T=116 I
where I is the 116×116 identity matrix.

Notes:

1. Maximal matrix first found by Baumert. [Bau]. It is a Williamson type Hadamard matrix.
2. N. J. A. Sloane's Library of Hadamard matrices lists a Williamson matrix of order 116.
3. J. Seberry's web site lists 1 Williamson matrix and 5 good matrices of order 116.
