Penetration of five tetrahedra
The interpenetration of five tetrahedra represents a star body that arises from a suitable combination of five tetrahedra that can be found in the dodecahedron .
This polyhedron was first described in 1876 by the German mathematician Edmund Hess (1843-1903).
The convex envelope is the dodecahedron. There are two mirror-image versions of this body.
