The lower bound for the diameter of the cube group was raised to 24q on 19 February 1995. I would be very surprised if Keith Randall presented a position requiring 24f. I don't know of any published results in metrics which include both slice and face turns. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Robert G.
