Abstract

Left-right symmetric massless quarks and leptons with the Pai-Salam index composed of fermionic and bosonic preons of N-plet of SU(N)subcolor are discussed. For NG=N/4 generations originated successively from preon pairs, “allowed” transitions within the same generation are at most ∼ 1/√N, for while those between generations are at most ∼1/N for N→∞.
