Let \(A=(a_{ij})\) be an integral matrix. We say that  \(A\) is \((0, 1, 2)\)-matrix if \(a_{ij}\in \{0, 1, 2\}\). There exists the Gorenstein \((0, 1, 2)\)-matrix for any permutation \(\sigma \) on the set \(\{1, \ldots , n\}\) without fixed elements. For every positive integer \(n\) there exists t...
