Polytetrahedron

Polytetrahedron is a term used for three distinct types of objects, all based on the tetrahedron:

A regular convex 4-polytope made up of 600 tetrahedral cells. It is more commonly known as a 600-cell or hexacosichoron. A polyform of regular tetrahedra. In origami, a polypolyhedron is "a compound of multiple linked polyhedral skeletons with uniform nonintersecting edges". There exist two topologically distinct polytetrahedra, each made up of four intersecting triangles.
