Web0. First we set M ~ for the matrix obtained by replacing all non-zero elements by 1. Start with a vector v ~ 1 having exactly one coordinate equal to 1 and all other coordinates zero. Consider v 2 = v 1 + M ~ v 1 and define v ~ 2 by replacing all non-zero elements (which are in fact strictly positive integers) of v 2 with 1 . ban12si
