Since you people are so quiet, I thought I should stir the pot a little.
Here's a challenge:
1) Name a uniform polyhedron with 8 faces, 18 edges, and 12 vertices.
2) Can you name a different
polyhedron with 8 faces, 18 edges, and 12 vertices?
Interesting coincidence, isn't it?
If you found the above too trivial, how about:
3) How many 4D uniform polychora can you name that contains the above two polyhedra as cells?
