Index Entry
Triacontrahedron:
"In the rhombic dodecahedron we have the unit vector radius at the center of the diamond faces.
It is only when the unit radius is at the sphere center that we get all the foldabilities where the value of the sphere becomes exactly 5.
With the unit radius at sphere center and with the 15 maximum great circles describing the triacontrahedron we get the only condition accommodating the unfoldable square of c^2 as a model to satisfy the Einstein equation."
