A unique chiral three-preon model of quarks and leptons is deduced without referring to the resulting composite states. This model is based on the gauged E/sub 6/xSO(10) preon symmetry where E/sub 6/ and SO(10) are the metacolor and color-flavor groups, respectively. The model has several notable features. The anomalies of the underlying theory are reproduced by pseudo-Goldstone bosons which acquire masses on the SO(10) scale. The model predicts three generations of ordinary quarks and leptons when SO(10) descends to the standard group through SU(4)/sub C/ x SU(2)/sub L/ x SU(2)/sub R/ but not through SU(5) x U(1). It can explain the correct ordering of the gauge hierarchy in terms of the preonic structure of the Higgs composites. The model predicts a large number of exotic fermionic composites at relatively low energies.
