Space and Family, my first paper on the subject, contains the main idea and a geometrical interpretation, which is still relevant at this time e.g. for inclusion of gravity. Spacetime is considered discrete at very small distances, with only permutation symmetry transformations remaining relevant. When a fermion tetrahedron moves through a gravitational field, the directions of its 4 tetrons are given by the 4-bein which defines the gravitational field at that point.
World of Tetrons contains a first approach to the formation of vector bosons from tetrons
Development of the Tetron Model
Some Remarks on the Tetron Spin Problem
The History of the Tetron Model (in german)
Chirality and Symmetry Breaking in a discrete internal Space, Internal space is interpreted as a vibrating 'crystal' or 'molecule' with pyritohedral symmetry, quarks and leptons being the normal modes of the vibrations.
Color and Isospin Waves from Tetrahedral Shubnikov Groups, an important supplement of the previous paper, in which internal spin waves are considered.
A microscopic Interpretation of the SM Higgs Mechanism, an extension to include the whole Standard Model symmetry breaking in the model
A Microscopic Approach to Quark and Lepton Masses and Mixings, an attempt to calculate the mass spectrum of quark and leptons
Particle Physics and Cosmology in the Microscopic Model, the latest paper on the subject, a complete review which includes also an interpretation of gravity in the tetron model
