Special for Brandon (bmenrigh). The topic - http://twistypuzzles.com/forum/viewto... Principle following: - I put the first edge through the L-layer, and I get out it through the B-layer. - I put the second edge through the B-layer, and I get out it through the L-layer. I put a edge to the "port" with wrong-color, and I get out it with correct-color.
