Tetrahedron Built from Rhombic Dodecahedra or Spheres
A tetrahedron can be built from rhombic dodecahedra or spheres. This Demonstration illustrates many interesting mathematical aspects, such as sphere packing, space filling, crystal lattices, sums of consecutive integers, and a relationship between tetrahedra and octahedra.
