That's an interesting method that should work well. In fact corner 3-

cycles are impossible. Still the problem of solving the edges

effectively remains. My short way to cycle 3-edges is like this:

(R u2)*2 R' u2 R' u' (R' u2)*2 R u2 R u

Edge 2-flip is like so:

(R u2)*2 R' u2 R' u (R' u2)*2 R u2 R u' (compare w d 3-cycle)

method for that bit and then solving the centers in 2 moves which can

mostly done with solving the first edge at the same time. And if you

want only RU moves for Guimond, that is possible too....

No, this is strictly <u,R> solving. No singular U turns allowed. U

is always turned dragging e layer along with it, making it u. And

also no physical orientation of the cube either :-)

Have fun!
