ButWhat is a rhombic triacontahedron?

The rhombic triacontahedron is a convex polyhedron with 30 rhombic faces. It is an Archimedean Dual solid, or a Catalon Solid.

The ratio of the long diagonal to the short diagonal of each face is exactly equal to the golden ratio f, so that the acute angles on each face measure 2 tan-1(1/f) = tan-1(2), or approximately 63.43. A rhombus so obtained is called a golden rhombus.

The rhombic triacontahedron is face-transitive, meaning the symmetry group of the solid acts transitively on the set of faces. In other words, this means that for any two faces A and B there is a rotation or reflection of the solid that leaves it occupying the same region of space while moving face A to face B. (This is one of many reasons the Ball of Whacks is so fun to play with!)
