Russian scientists, adding the dodecahedron structure to Sanderson's discovery, found that the greatest earthquake lines were on the dodecahedron grid.
However, the own arrangement of the six-dipole system doesn't define as yet the full dodecahedron symmetry, First, we have to specify in a way the angular position of this system relative to the cube by means of photon oscillation counting, Second, the reciprocal angular positions of the quarks themselves isn't specified completely, because the equilibrium of their arrangement under the strong interaction would not be destroyed in deformations leaving the opposite quarks on their common diagonal upon its rotations,
In case of rotating the pentagons of the dodecahedron, so that they no longer have a common edge, but a common point, an irregular polyhedron with 60 equal edges is obtained, composed of 12 initial pentagons and 20 equilateral triangles in addition.
This position both resolves the original difficulties which arose in dealing with numbers and explains why we might regard numbers, triangles, squares, dodecahedrons, and so on, as the subjects of their respective sciences in the first place: for they are subjects found within those sciences, albeit not ultimate subjects.
More accurately, he investigates the plastic properties of the regular pentagon and the regular twelve faced complexes constructed out of pentagons: the dodecahedrons.
