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:

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.
