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

4-polytope
Videos
In geometry, a 4-polytope is a four-dimensional polytope. It is a connected and closed figure, composed of lower-dimensional polytopal elements: vertices, edges, faces, and cells. Each face is shared

…faces of the 120-cell, whose universal cover gives the regular honeycomb {5,3,3,5} of 4-dimensional hyperbolic space. 57-cell – an abstract regular 4-polytope constructed from 57 hemi-dodecahedra. 600-cell - the dual 4-polytope to the 120-cell…
