Dodecaplex

Polychorons are the 4D version of polyhedrons (in general, for arbitrary dimensions, these are called polytopes). A dodecaplex is a uniform polychoron composed 120 dodecahedral cells. These cells can be divided into 12 rings (Hopf fibrations) of 10 cells each. One way to visualize a polychoron is to apply a 4D to 3D stereographic projection to it. This picture shows a stereographic projection of the complete dodecaplex.
