4D Euclidean space
Polytope of the Month
This month, we continue with our exploration of the so-called ursatopes, a generalization of the tridiminished icosahedron to higher dimensions, by taking a look at the octahedral cousin of last month's Polytope of the Month. This is the octahedral ursachoron:
This polychoron has a surface with an octahedron, 8 tridiminished icosahedra, 6 square pyramids, and a cuboctahedron. Head on over to the octahedral ursachoron page to learn more about the structure of this interesting CRF polychoron. Its full coordinates are available, as usual.

Ever wondered how to visualize 4-dimensional space? It's not as difficult as it may sound at first! Read the 4D Visualization pages to find out more.
These pages contain information about various 4D objects and many images of their projections into 3D.
