	<span style="line-height:1.5;">A previous spin 1/2 preon model for the substructure
of the standard model quarks and leptons is complemented to provide particle
classification group, preon interactions and
a tentative model of black holes. The goal of this study is to analyze a phenomenological theory of all interactions. A minimal amount of
physical assumptions are made and only experimentally verified global and gauge
groups are employed: SLq(2), the three of the standard model and the full
Poincar¨¦ group. Gravity theory with torsion is introduced producing an axial-vector field coupled to preons. The mass of the
axial-vector particle is estimated to be near the GUT scale. The boson
can materialize above this scale and gain further mass to become a black hole
at Planck mass while massless preons may form the horizon. A particle-black
hole duality is proposed.</span>
