What is a god number?
The term “God’s number” is sometimes given to the graph diameter of Rubik’s graph, which is the minimum number of turns required to solve a Rubik’s cube from an arbitrary starting position (i.e., in the worst case). Rokicki et al. (2010) showed that this number equals 20.
What is God’s number for 3×3?
That number is 20, and it’s the maximum number of moves it takes to solve a Rubik’s Cube. Known as God’s Number, the magic number required about 35 CPU-years and a good deal of man-hours to solve. Why?
