Good matrices of even order

We generated good matrices in Jennifer Seberry's research. We can generated good matrices of even order.

define for good matrices A,B,C,D:four (1,-1) matrices,order m.

・NM^T=MN^T (N,M in A,B,C,D)

・AA^T+BB^T+CC^T+DD^T=4mI

・(A-I)^T=-(A-I),B^T=B,C^T=C,D^T=D

good matrices of even order are as follows:
