## Abstract The representation of an __N__โelectron Schrรถdinger Hamiltonian on an orthonormal, spinโfree (freon) orbital product space is exactly modeled by a secondโdegree polynomial in the infinitesimal generators of the unitary group. Symmetry adaptation of the orbital product space with respect
