Permutahedron

This is a representation of the permutahedron, a geometric representation of the permutations on 4 letters of order 4! = 24. Here we see in black 3 great circles on the sphere dividing the sphere into 24 chambers. The center of each of these chambers is represented by a red dot and the red dots are connected with a blue line if one can be obtained from another by reflecting it across one of the great circles.
