Excavating a dodecahedron by 12 peppies and then Stott expanding that outcome, thereby blowing up every vertex into pentagons, the outer (original) edges into squares, and the triangles into hexagons: this is how this very pleasing tetraform acoptic polyhedron, mentioned in 2022 by T. Dorozinski, could be derived.
This tetraform acoptic polyhedron has the following vertex radii:
R( x3f5x ) = sqrt[47+20 sqrt(5)]/2 = 4.788563 R( f3o5u ) = sqrt[37+14 sqrt(5)]/2 = 4.132340 R( o3o5F ) = sqrt[27+12 sqrt(5)]/2 = 3.668542 R( E3o5x ) = sqrt[27+ 8 sqrt(5)]/2 = 3.349946 where: E = 2f-x = f+v = sqrt(5), F = x+f = ff
