96×96 {-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=96 I
where I is the 96×96 identity matrix.

Notes:

1. Maximal matrix first reported by Hadamard [Had].
2. N. J. A. Sloane's Library of Hadamard matrices has a Hadamard matrix of order 96.
3. The list is presumably not complete.
