| Abstract: | We give an algorithm to obtain formulae and values for minors of Hadamard matrices. One step in our algorithm allows the (n−j)×(n−j) minors of a Hadamard matrix to be given in terms of the minors of a 2j−1×2j−1 matrix. In particular we illustrate our algorithm by finding explicitly all the (n−4)×(n−4) minors of a Hadamard matrix. |
