Nature is inherently eight-dimensional, and the first four of these dimensions are the four planes of symmetry of the minimum structure of Universe-the omnitriangulated, equi-vector-edge tetrahedron. In respect to the conceptual pre-time-size tetrahedron’s volume taken as unity 1, with its six unit-vector-edge structure, the always conceptual-independent-of-size family of primitive, pre-time-size, least complex polyhedra have the following exact volumes-the vector-triangulated cube 3, the octahedron 4, the rhombic triacontahedron 5, and the rhombic dodecahedron 6. When the size information is introduced, it occurs only as frequency of modular subdivision of each unit vector structuring of the primitive family’s respective 1-, 2-, 3-, 4-, 5-, and 6-tetravolumes. Frequency to the third power, F3 , values then multiply the primitive, already-four-dimensional volumetric values. In physically realized time-size each has therefore 4 + 3 = 7 dimensions, but since each system is inherently independent in Universe and therefore has spinnability, one more dimensional factor is required, making a total of eight dimensions in all for experientially evidencing physical reality.
