At each node in the tetrahedral vacuum lattice there are 2x three lattices connected.
However by the rotation of each lattice nodes, (30 degr. between tetrahedrons ) there only are two choices available left or right. for a photon to chose and for each wave function collapse, because these lattice are the most easy to connect. ( 30,degr left or right)
