  It is shown that the SU(3) symmetry of the fermion dynamical symmetry model
is essentially preserved even for highly nondegenerate spherical
single-particle energies. The breaking of SU(3) symmetry by single-particle
energy terms for either normal deformation or superdeformation occurs only
through an indirect Pauli effect and is significant only when the spherical
single-particle splitting within shells is artificially large relative to that
observed experimentally.
