Say you have four symbols, like a heart, spade, club, and diamond. There are 6 ways to arrange these four symbols on the corners of a square, not including rotations but including mirror images. Similarly, there are eight ways to arrange three of the symbols on the corners of a triangle. That's just enough to cover a cuboctahedron - can they do it with adjacent corners matching up?
I think this would make an interesting Skewb sticker mod.
