On Minors of Maximal Determinant Matrices

Brent, Richard; Osborn, Judy-Anne


By an old result of Cohn (1965), a Hadamard matrix of order n has no proper Hadamard submatrix of order m > n/2. We generalize this result to maximal determinant submatrices of Hadamard matrices, and show that an interval of length ~ n/2 is excluded from
