It appears that Singmaster, Thistlethwaite, and just about all the cube

hackers I know at and around Stanford consider anything you can do

with one wrist motion to be a single twist. 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?)
