4D Euclidean space
13 Jun 2011: We're a bit late for this month's polytope again, but here it is:
This is the cantellated 5-cell, a member of the sweet and simple 5-cell family of uniform polytopes, shown in two 4D viewpoints. It is bounded by 5 octahedra, 5 cuboctahedra, and 10 triangular prisms.

We're a bit late for this month's polytope, but it's never too late! This month, we present another member of the beautiful family of uniform polychora with 120-cell symmetry:
Behold, the rectified 120-cell! This “mugshot” shows the subset of its 600 tetrahedral cells that lie on its “northern hemisphere”, colored in 7 layers. It also has 120 icosidodecahedral cells, not shown here. Find out more in the rectified 120-cell page!

For the month of April, we present the runcinated 24-cell, another beautiful member of the 24-cell family of uniform polytopes, bounded by 48 octahedra and 192 triangular prisms.
