Five Intersecting Tetrahedra

Geomag model. This polyhedron is one of the 13 Archimedean solids. It has 20 regular triangular faces, 30 regular square faces, 12 regular pentagonal faces, 60 vertices and 120 edges.


The hyperdodecahedron is a finite regular four-dimensional polytope. It is also known as the 120-cell or hecatonicosachoron, and is composed of 120 dodecahedra, with 3 to an edge, and 720 pentagons. The 120-cell has 600 vertices and 1200 edges. It is one of the six regular polychora.
