Niklas

The Niklas is a common commutator applicable to many puzzles. Lars Petrus coined the name as a last layer corner permutation algorithm for his method.
The Niklas may be written as R U' L' U R' U' L (U), which is the commutator [R, U' L' U], or [R, U': L']
The Niklas can also be performed in various ways using a combination of slice turns and face turns. This provides 8move commutators that can cycle 3 pieces of any type. One form is particularly helpful for solving a few centers between two remaining faces at the center stage of the reduction method for cubes larger than 3x3x3.
Examples
(x') M' U' R U M U' R' U (x) ... does ELL, mirror and reflections makes four algs.
(x') r U' R U r' U' R' U (x) ... same for big cubes, change r to any slice and you have many combinations.
