# The 'Granthahedron': The World's First (Known) Pentagonal Hexakaidecahedron

Newly DISCOVERED Geometry (January 30, 2021)--The 'Granthahedron': The World's First (Known) Pentagonal Hexakaidecahedron. A Sixteen (16)-sided Polyhedron made up of 8 identical Irregular (Diamond-Shaped) and 8 Identical Regular Pentagons. (*NOTE: Recall that the planet Mercury's Year--Solar Orbital Period--is 88 Earth Days). In Greek the technical name for this would be a Pentagonal Hexakaidecahedron (meaning 16 sides/faces). I looked among all known three dimensional solids and could not find any records of this shape (including Johnson Solids, Archimedean, Catalan and Duals). I am also quite sure that this geometric structure will "close" also with the proper angles. As this solid matches my birthday 5.16 (16 Pentagonal (5) sides), I decided to name this one (the first of many yet unnamed geometric structures), the 'Granthahedron'. It also possesses a sum of interior angles of 8,640° (recall that the Sun's Diameter is 864K miles and we have 86,400 seconds in each (24 hour) day. *Note, this new geometry was found using 8-point perspective (similar to the Gyrobicupola (not Metatron's Cube) that I found using the same structure a few months ago. I wonder what else will be revealed in the coming days as new geometry seems to always be accompanied with new mathematical and physics related understandings of the Universe...
