Sicherman dice
From Wikipedia, the free encyclopedia
Sicherman dice are the only other pair of 6-sided dice bearing only positive integers which have the same probability distribution as a pair of normal dice. The faces on the dice are numbered 1, 2, 2, 3, 3, 4 and 1, 3, 4, 5, 6, 8. These dice were discovered by Colonel George Sicherman, of Buffalo, New York and were originally reported by Martin Gardner in a 1978 article in Scientific American. Later, in a letter to Sicherman, Gardner mentioned that a magician he knew had anticipated Sicherman's discovery.
