UF and RBL generate the whole cube group
Submitted by rokicki on Sat, 03/20/2010 - 13:43.The two simple generators UF and RBL (without any rotations) generate the whole cube group.
It's surprising to me that these two very simple generators suffice.
It's easy to see no shorter set of generators (expressed in face turns) suffice because you need at least five faces.
