Description
5-Player Go First Dice are available from https://www.mathartfun.com/dSpecial.html
Our five player set was discovered by Paul Meyer. Carl Hoff and I did the 3D design and they were produced by The Dice Lab, which is Robert Fathauer and me. The positioning of the numbers was derived from a numbering of the deltoidal hexecontahedron d60 by Paul McGuire.
The four player set was discovered by Eric Harshbarger, Robert Ford, and James Ernest, and is available from MathsGear at https://mathsgear.co.uk/collections/dice/products/go-first-dice
The three player set was discovered by Robert Ford.
There are five player sets with fewer faces, but the only known solutions use dice of different sizes. Bram Cohen found a solution with one d20 and four d36 dice.
