Sune is the most widely recognized name for the OLL case in which the edges are oriented and three corners are twisted counterclockwise, and also for the algorithm which solves it.
The term was coined by Lars Petrus for his method. Sune is a male name in Sweden and is an iron age form for 'the son'; in modern Swedish that is 'sonen'. It is pronounced "soon-eh" ([suːnɛ]), but in cubing it has become far more common to be pronounced "soon" ([suːn]).
The Sune is a 2-gen algorithm that affects the last layer of a Rubik's Cube, and can be applied to other puzzles. It is most canonically written as
The Sune can be written as a pure commutator, but is most commonly recognized as a conjugated commutator or a sequence of two commutators.
An alternative name: the Anti-Chair
Anti-Sune is also known as the chair. This is because of a famous beginner mnemonic device. This mnemonic device consists into repeating this little story: "He stands up (R), goes far away (U2), his chair falls (R'), he comes back next to his chair (U'), he straightens his chair (R), he goes back on his chair (U') and he sits down (R')." Logically, as Anti-Sune is also called Chair, Anti-Chair is an alternative name of Sune.
