Sažetak
Group properties of a very general class of SUSY preon models, including already published simple models, are studied. Yukawa mass terms and the resulting proton decays are investigated. Special attention is given to interesting models based on the chain E6 ⊃ SU(2)Hc ⊗ SU(3)c ⊗ U(l)3. In those models grand unification requires either extensive symmetry breaking or an assumption that second and third generations are excited states of the basic structure. The proton decay is characterized by the four particle final state p → n-e+e +ve. It is very difficult to construct SUSY strong coupling model which satisfies a set of constraints (given in the text) which are inspired by physical considerations.
