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.
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 letters 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.
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...
