How do I go about the calculation of the number of PLLs? This is for a school essay. I've done this:
4!x4! to give the total number of possible permutations.
4!x4!/2 to get rid of the impossible ones.
4!x4!/2/4 to get rid of symmetry.
That gives 72 PLLs but that's far too many.
It will get very slow at the start becuase your lookahead is hardly better than before and your TPS is far slower. However after time you should increase your lookahead ability and then you can gradually increase your TPS.
Intuitive F2L ends up the same thing as alg F2L. Intuitive F2L users need to develop the lightning-quick response and look ahead ability that alg F2L gives, and alg F2L users need to develop the flexibility that Intuitive F2L gives. I would personally use algorithms to work out concepts of the...
This is an AMAZING scramble! Got a sub-10 first try, sub-8 next. Cross colour on top:
R' D L2 D' R L' U' D L' D U B2 F' D2 B' D' R2 B' F L2 B F' R2 D' F2
(f2 u) L2 U L F L' U L U F R' F' (u) R U2 R' U R U R' (F2L and OLL skip: 18 moves)
U (u) R U R' U' R' F R2 U' R' U' R U R' F'...
