Re:Which 25 moves?

On: Rubik's Cube Proof Cut To 25 Moves

What are these magic 25 moves that can solve a rubik's cube regardless of starting position? Actually, he gave a a useless proof. First he found ( easy part) the number of all possible scrambled version one can have. Then he showed that if you start with a perfect cube, and start a count: First find all possible numbers of scrambled version you can get by making one move, then all possible scrambled version that you can get by two moves which cannot be obtained with one move. Add these two to get maximum possible numbers of scrambled cube obtained by scrambling a solved cube with 1 or 2 moves, and then find the possible number of scrambled cubes with three moves, and so on. His computer aided calculations showed that by 25 moves, his count reached the maximum possible combinations of scrambled cube-1. -1 is because one scrambled version is actuality the solved version. This may be an interesting result, but useless in as far as trying to solve it.
