Geometry
Note: Stars, Triangles, Triunes, Hexagons, Centroids (as triangles with a centroid and center a triangle also with a centroid) etc are HIGHLY HYPERLINKED, so what is seen in one is found in the other measurements
This site mostly uses the non-centered pentagonal due to its indexing with significant numbers.
Its geometric progression is also more accurate with the natural progression of man.
The rate of head to body length growing proportions.
