Last Three Corners
Last three corners, abbrevaited L3C (or 3LC), is a method that solves three of the last layer corners preserving all the rest, a sub group of L4C, ZBLL and ZZLL.
The group have 27 cases including solved, 3*3 orientations and 3 permutations. Most of the cases, 18 are pure 3-cycles, the rest are pure twists U, T, L, S and -S. Some of the twist occures 2 times (U, T and L) and the T-twist is the same as the U-twist if the puzzle is re oriented. Subtracting the duplicates and the solved case it will be 22 cases left.
The pure twist you can find at the Corner orientation page and two of the 3-cycles are only permutation, look at A-PLL a and b at the PLL page for those.
The rest of the 3-cycles will be listed here...
Usage: besides L4C it is useful for FMC and the 3-cycles are nice for Freestyle BLD.
Cases
The naming system used here is adapted to BLD, the ULB corner is always the solved one and URF is the 'buffer' with U as the buffer sticker. The piece in the buffer will go to two places, either URB or UFL and the sticker in U will go to any of the three stickers on each goal position and that sticker is in uppercase, the other two letter will be in lower case.
Example: CW A-PLL will be Ulf-Urb (the last piece will always go to the buffer position so that will not be in the name and CCW A-PLL will be Urb-Ulf.
