Each square complex matrix is unitarily similar to an upper triangular matrix with diagonal entries in any prescribed order. Let A = [a ij ] and B = [b ij ] be upper triangular n Γ n matrices that β’ are not similar to direct sums of square matrices of smaller sizes, or β’ are in general position an
