Rubik's cube

The study builds on the work of a veritable pantheon of Rubik's researchers, starting with Morwen Thistlethwaite who in 1981 showed 52 moves were sufficient to reach the solution from any given Cube position.

By May 1992, Michael Reid showed 39 moves was always sufficient, only to be undercut a mere day later by Dik Winter, who showed 37 moves would work.

The current world record holder is Dutch Erik Akkersdijk who successfully solved the puzzle in just 7.08 seconds.

7.08 seconds, tooo fast.
