A low-energy electroweak symmetry group is proposed from an E/sub 6/ x E/sub 6//sup '/ preon model which leads to SU(3)/sub C/ x SU(2)/sub L/ x SU(2)/sub R/ x U(1)/sub Y//sub L/ x U(1)/sub Y//sub R/ where SU(2)/sub R/ can either be the usual left-right-symmetric model group or an ''inert SU(2)/sub R/'' with electromagnetically neutral gauge bosons. Additional discrete symmetries proposed in E/sub 6/ models are obtained as a transformation of preons and conservation of quantum numbers. Among the results of this model are (i) the existence of two effective scales, metacolor (..lambda../sub M/approx.10/sup 14/ GeV) and hypercolor ..lambda../sub H/ (1 TeV), (ii) preon substructures for vector leptons (both right and left handed), (iii) B-L number (1/3 for the g quark, (iv) neutral composite Higgs scalar bosons, and (v) small mixing angles between (E/sub d//sup -/,e/sup -/),(d,g) states and neutrino mixing.
