• Hi :-) 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.

Hi :-)

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)

• Hmm, if you want to solve corners first, I suggest doing Guimond method for that bit and then solving the centers in 2 moves which can mostly done with solving

Hmm, if you want to solve corners first, I suggest doing Guimond
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....

• Hi :-) No, this is strictly solving. No singular U turns allowed. U is always turned dragging e layer along with it, making it u. And also no physical

Hi :-)

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!
