The choice of number you can do this with is quite small - only 2!

It's amazing that if you know enough non-essential math, you will know that you cannot end an exclamatory sentence with a number, or you will be made fun of on the internet, but you have to be such a nerd to know you can't do that.

Polyhedron of the Day #100: Escher's solid

Escher's solid is a polyhedron, depicted in M.C. Escher's Waterfall. It has 48 faces, 72 edges, and 26 vertices. It is visually identical to the first stellation of the rhombic dodecahedron and the compound of three flattened octahedra. It can tessellate space to form a stellated rhombic dodecahedral honeycomb. A puzzle known as the Yoshimoto Cube is based on this fact. Its convex hull is a cuboctahedron.
