[1][2] The dice are intended for fairly deciding the order of play in, for example, a board game.
Two coins (2-sided die) can be used: An optimal and permutation-fair solution for 3 six-sided dice was found by Robert Ford in 2010.
An optimal and permutation-fair solution for 4 twelve-sided dice was found by Robert Ford in 2010.
Alternative optimal configurations for mismatched dice were found by Eric Harshbarger.
A not-permutation-fair solution for 5 sixty-sided dice was found by James Grime and Brian Pollock.
