The method of Part I is applied to the problem of finding the lowest antisymmetric eigenfunction of the wave equation for n electrons without spatial symmetry, and the lowest antisymmetric eigenfunction of given multiplicity. Knowledge of the multiplicity of the ground state is not needed. Theorem 3 of Part I, which proves the equivalence of the central stationary condition to a minimum condition, is extended to cover the present case.
