## Submission + - A Proof of the Rubik's Cube Solution (mit.edu) 1

*Over thirty years ago, the Rubik's Cube was born. And now it has been mathematically proven that a cube with N squares per row in any given configuration has a solution with the maximum number of moves proportional to (N^2)/(log N). This paper explains why we've seen the most popular configuration (N = 3) of Rubik's Cube shrink in maximum number of moves from 25 to 23 to 20 and you might even see it settle in at 19.*
