Hi there,
I've been interested in the Rubik's cube for a couple of years now and have successful solved it a few times now with some help from various algorithms.
I have a friend who swears that, a few decades ago, she knew a fixed sequence of moves (i.e. turns) that would solve the cube regardless of it's starting configuration. It has been somewhat of an on going debate since she cannot remember the precise sequence of moves, and I do not think that such a sequence of moves is possible, nor have I been able to find any evidence that such a sequence can exist.
To be clear, such a sequence of turns would have to be able to:
1) Solve the cube from any configuration, including a solved cube, or any step along with way if you decided to start over
2) Not require any decisions on the part of the solver, i.e. once you know the moves, it always works.
In addition, I recently chatted with the man who she remembers teaching her the move sequence who confirmed everything she said about teaching her a fixed sequence of moves to solve the cube, but also not remember the sequence himself.
If you know of any such sequence of moves, or could explain why such a sequence could not exist (not just say it can't), I would be most interested.
Thanks!
