  George Sicherman discovered discovered that two cubic die numbered 1-2-2-3-3-4 and 1-3-4-5-6-8 have the same sum probabilities as do the standard set of cubic dice (1-2-3-4-5-6). Since George Sicherman's discovery, other mathematicians have also set about to discover other dice relationships, more so with the assistance of technology. Ed Pegg Jr. is one of them. He shows you how to calculate the odds, and how to determine what different numbers could be on the faces to give the same odds. You can see more explorations of Sicherman Dice here.
