I hold the cube so the bottom looks like this: . . a . . . . b . . . c . . . . and do this sequence: F' b2 L2 / R' D r' D' R D r D' / L2 b2 F Capital letters are outer slices. Small letters are inner slices. The slashes are just to show the different parts of the sequence. The middle part, if performed alone, will cycle three edges. The first part of the sequence positions the cubies we want to move into the positions of the cubies that are cycled by the middle sequence. The last part of the sequence simply reverses the first part. Left view of cube: . . . . . . . a . . . . . c b . b2 R2 / L D' l D L' D' l' D / R2 b2 Bottom view of cube: . . a . c . . b . . . . . . . .

F' b' L2 / R' D r' D' R D r D' / L2 b F Here are some other three cycles you may find useful: R' D l D' R D l' D' R' D L D' R D L' D' r' D l D' r D l' D' -- mailto:davidbarr@iname.com http://www.concentric.net/~Davebarr/
