Since this gives a more accurate measure of how complicated a sequence is, I'm happy with it. Why do you folks at MIT insist that you're right and the world is wrong? (I admit it complicates the notation. My own cube notation uses two chars per twist, one being the face and the other being the direction: left-arrow for counterclockwise, right-arrow for clockwise, down-arrow for 180 -- isn't extended ASCII wonderful?) -- Don.
