Last Three Corners
From Speedsolving.com Wiki
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 and T) 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...
