  A specific new quark permits that flavor generations constitute a
representation of the 3-dimensional SU(3) symmetry that characterizes the Z(3)
orbifold. In this context, color and supergravity bind triplets and 4-tuplets
into composite fields of spin 3/2 and spin 2; and the symmetry E(8) that
characterizes (the observable sector of) 10-spacetime is interpreted as having
reduced to SU(5)XSU(3), where SU(3) refers to the 3-dimensional symmetry
described above and SU(5) consists of colors and of isotopic spin classes that
are devoid of color and hypercharge. In this context, supergravity interactions
occur to color bound quarks that are experiencing asymptotic freedom within
triplets. Quark-lepton transitions are produced, but quickly reverse,
preserving the triplets. The symmetry consisting of six quark classes and six
lepton classes is also maintained because the predicted quark is an anomalous,
left-handed version of the strange quark.
