Eternity Ii Puzzle Views
The Eternity II puzzle, aka E2 or E II, is a puzzle competition which was released on 28 July 2007.[1] The competition ended at noon on the 31st of December 2010. It was published by Christopher Monckton, and is marketed and copyrighted by TOMY UK Ltd. A $2 million prize was offered for the first complete solution.
The number of possible configurations for the Eternity II puzzle, assuming all the pieces are distinct, and ignoring the fixed pieces with pre-determined positions, is 256! × 4256, roughly 1.15 × 10661. A tighter upper bound to the possible number of configurations can be achieved by taking into account the fixed piece in the center and the restrictions set on the pieces on the edge: 1 × 4! × 56! × 195! × 4195, roughly 1.115 × 10557.
The Eternity II puzzle was designed by Monckton in 2005, this time in collaboration with Selby and Riordan, who designed a computer program that generated the final Eternity II design.[6] According to the mathematical game enthusiast Brendan Owen, the Eternity II puzzle appears to have been designed to avoid the combinatorial flaws of the previous puzzle, with design parameters which appear to have been chosen to make the puzzle as difficult as possible to solve. In particular, unlike the original Eternity puzzle, there are likely only to be a very small number of possible solutions to the problem.[7] Owen estimates that a brute-force backtracking search might take around 2×1047 steps to complete.

Eternity is a tiling puzzle created by Christopher Monckton and launched by the Ertl Company in June 1999. Consisting of 209 pieces, it was marketed as being practically unsolveable, with a £1 million prize on offer for whoever could solve it within four years. The prize was paid out in October 2000 for a winning solution arrived at by two mathematicians from Cambridge.[1] A second puzzle, Eternity II, was launched in Summer 2007 with a prize of $2 million.[2]
