A note of values of minors for Hadamard matrices

Abstract

In this note we present a formulae for all possible values of $(n-j)\times (n-j)$ minors of an Hadamard matrix of order $n$.

The result has presented in 'Exotic complex Hadamard matrices, and their equivalence'( https://link.springer.com/article/10.1007/s12095-010-0021-3 ).Thanks to Prof. Ferenc for his notice
