Rhombic tricontahedron and its derivatives. The rhombic diagonals are in the ratio of 1/F
Rhombic tricontahedron, 30
rhombi (Kepler)- a "belt" of 10 rhombi- rhombic
icosahedron,
20 rhombi (Fedorov, in 1885)- a "belt" of 8 rhombi -
rhombic dodecahedron "of the second kind" (Bilinski, in
1960). Rhombictricontahedron can be inscribed in a sphere, but
