The density matrix f (2) which results from minimizing ( N /2) tr H (2) f (2) subject to the eigenvalue condition on the one‐matrix is put into the G ‐matrix condition. The resulting large negative eigenvalues of the latter indicates significant improvement upon enforcement of this condition. A method of calculation and conditions beyond the G ‐matrix condition are discussed.
