That took me a few reads to understand, so allow me to explain another approach to this problem.
I use this method and I believe many other PLL users also do. But just to warn you, it is tailored towards a specific choice of G-Perm algs. First, I determine that it is indeed a G-Perm by readily ruling out everything else according to the location of "blocks" (c/e pairs). Assuming it is a G-Perm, I hold "the pair" (typical teamBld lingo for the two corners that are correct relative to each other), on the left. It is personal preference whether to just re-grip, or pre- adjust U and re-grip. Next (or really, at the same time) find "the block" (there should be precisely one and it should be on the r-layers). It can either be on the back, "upper right", "lower right", or front. (This is then sometimes numbered G1,G2,G3,G4, respectively for teamBld calls.) If the block is on the back (UB+uBR), I start with the (R2u') trigger. If it is on the "upper right" (UBR+UR), I start with a (R'U'R) trigger. If it is on the "lower right" (UR+uFR), I start with a (RUR') trigger. If the block is on the front (uFR+UF), I start with the (R2'u) trigger. Notice the symmetry in this method. *Gosh, I do hope you use similar algs... -Doug --- In [email protected], "Dan" <[EMAIL PROTECTED]> wrote: > > Hi Mike, > > I use 2 tricks which I now see simultaneously, but this didnt come > with lots of practice! > > First I locate the only connected pair of stickers around the side > of the top layer.
