In some versions of the legend the priests are only allowed one move per day, though even allowing one move per second would require more than 500 billion years to complete the task. When the priests finally succeed in transferring all of the disks, the world will end. If the original “needle” (peg) was a tower with 64 disks, the number of transfers would be 2 64 − 1, or 18,446,744,073,709,551,615 this is exactly the same number required to fill an 8 × 8 checkerboard with grains of wheat, 1 on the first square, 2 on the second, 4 on the next, then 8, 16, 32, and so forth.Īccording to a legend of obscure origin, there exists a Vietnamese (or, sometimes, Indian) temple or monastery where priests have been shuffling golden disks between three pegs for many centuries. Thus for 8 disks, the puzzle requires 2 8 − 1, or 255 transfers. The Towers of Hanoi, also called Tower of Brahma, Lucas Tower, or more simply, the pyramid puzzle, is a mathematical game using three rods and various. It can be shown that for a tower of n disks, there will be required 2 n − 1 transfers of individual disks to shift the tower completely to another peg. The puzzle of the Tower of Hanoi is widely believed to have been invented in 1883 by the French mathematician Édouard Lucas.
