If the particle content of a supersymmetric SU(3) x SU(2) x SU(2) x U(1) gauge model is extended to include new quarks and leptons as given by the 27 representation of E/sub 6/, an unconventional left-right assignment is possible, resulting in a number of desirable features, one of which is a simpler Higgs-boson structure. Also, a conserved multiplicative quantum number can be defined as a generalization of the usual R parity in most models of supersymmetry. This prevents W/sub L/-W/sub R/ mixing and makes possible a massless Dirac neutrino whose right-handed component is effectively inert. From neutral-current constraints based on present experimental data, lower bounds of about 180 and 210 GeV are obtained for the second W and Z bosons of this model, respectively.
