Sune
Algorithm
The Sune (soon-ay) is a well-known 2-gen algorithm that affects the last layer of a Rubik's Cube, and can be applied to other puzzles. The term "Sune" was coined by Lars Petrus for his method, and is the most widely recognized name for the sequence of moves.
The Sune is most canonically written as R U R' U R U2 R'
There are many algs related to and/or derived from the Sune, such as its inverse, the Anti-Sune.
The Sune can be written as a pure commutator, but is most commonly recognized as a conjugated commutator or a sequence of two commutators.
Usage of the algorithm: Most often a OLL in the Fridrich Method or a CO for any cube, but also a COLL in the Vandenberg-Harris Method, a CLL, a ZBLL and besides that you can use it to to do 3-cycle edge permutation if corners are ignored and more...
Case
All cases of the last layer that has got three corners twisted is a 'Sune case'.
