(LAST NIGHT 9-1-21): A NEW GEOMETRIC POLYTOPE comprised of REGULAR (equilateral) HEPTAGONS.
It’s made only of Regular Heptagons (16 of them), (14 squares), (4 Silver Ratio Rectangles) and (8 Isosceles Triangles). 42 total sides…..(divisible by 7). It’s Angular Sum is 22,320°…..and the square root of this is 149°23’…..1.4920 = The Newly Discovered Platinum Ratio….. derived from the Silver Ratio (2.4142) /Golden Ratio (1.61803) = 1.4920 (Platinum Ratio). So far, this new Polytope appears to be entirely novel to the research/geometric literature. This shape closely resembles that of a BRAIN 🧠. Interesting that the Granthahedron is shaped like a HEART and this one is shaped like a BRAIN 🧠.
What shall we name this one??? The “Brain-a-Hedron”? Please comment!!
