The first six separate, regular polygons in the inner Tree of Life have 36 corners and the seventh polygon has 12 corners. The counterpart of these 48 corners in the tetrahedron whose faces are constructed from 12 tetractyses are the 12 red hexagonal yods at their centres and the 36blue hexagonal yods that line their sides. The first three polygons have 12 corners that correspond to the 12 blue hexagonal yods that line the six edges of the tetrahedron. The next three polygons have 24 corners that correspond to the 24 blue hexagonal yods lining the internal sides of the 12 tetractyses. The 12 corners of the dodecagon correspond to the 12 red hexagonal yods at the centres of these tetractyses. Both the 48 corners and the 48 hexagonal yods display the divisions: 48 = 24 + 2424 = 12 + 12These are characteristic of holistic systems.
