The fact that the colored squares on a Rubik's Cube have 43,252,003,274,489,856,000 different possible configurations may come as little surprise to those who have spent many an hour puzzling over one; however, the knowledge that each configuration may be solved in 20 moves or less may. An international team using Google's computers to investigate millions of configurations determined that the so-called "God's number," or the fewest number of moves it would take an all-knowing being to solve the hardest configuration of a Rubik's Cube, is 20. In fact, only 300 million arrangements require a full 20 moves. The majority of solutions take between just 15 and 19 moves to solve.
