Tetrons - a possible Solution to the Family Problem
  A model is presented, in which fermion and vector boson states are constructed from constituents (tetrons). The model encodes all observed structures and phenomena of elementary particle physics in group theoretic items of the permutation group S_4. Details of the model like symmetry breaking, distribution of charges and mass generation are worked out. As a sideproduct a deeper understanding of parity violation is obtained.
