Abstract
We found the lower bounds on the number of ones in fully indecomposable (0, 1) matrices such that their permanents are equal to the determinants of matrices obtained by a suitable change of signs in the entries. We consider separately general case and the case of symmetric matrices with vanishing diagonals.
