120-cell
Videos
In geometry, the 120-cell is the convex regular 4-polytope with Schläfli symbol {5,3,3}. It is also called a C120, dodecaplex, hyperdodecahedron, polydodecahedron, hecatonicosachoron, dodecacontachoro

In geometry, the 600-cell is the convex regular 4-polytope with Schläfli symbol {3,3,5}. It is also known as the C600, hexacosichoron, hexacosihedroid and hypericosahedron. It is also called a tetrapl

…has 12 pentagonal facets, with 3 around each vertex, the dodecaplex has 120 dodecahedral facets, with 3 around each edge. Its dual polytope is the 600-cell. The 120-cell incorporates the geometries of every convex regular polytope in the first four dimensions (except the polygons {7} and above). As the…
100 tetrahedra in a 10×10 array forming a Clifford torus boundary in the 600 cell. Its opposite edges are identified, forming a duocylinder.
