DIAMANT problem

Matrix inequalities

Let n ≥ 2. We look for three n x n matrices A,B,C over the non-negative integers with the following properties:

Context of the problem

Several techniques have found solutions of the above problem, but not really systematically, and all requiring quite some computation time. Moreover, we should like to know the smallest n for which there is a solution.
