Information about the method
Proposer(s): Lars Petrus
Proposed:
Alt Names: S, Chair', Anti-Chair
Variants: Antisune
No. Steps: 1
No. Algs: 1
Avg Moves: 7 HTM
Purpose(s):

The term Sune; (soo-nay), was coined by Lars Petrus for his method, and is the most widely recognized name for the sequence of moves and the case. Sune is a male name in Sweden and is a iron age form for 'the son', in mordern Swedish that is 'sonen'.

The mirror/inverse alg/case is named Antisune (or Anti Sune). Using double layers for the first and last moves it is called a Fat Sune (Rw U R' U R U2 Rw').

Algorithm

Sune is a 2-gen algorithm that affects the last layer of a Rubik's Cube, and can be applied to other puzzles.

The Sune is most canonically written as

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 as an OLL in the Fridrich Method or a CO for any cube, but also as a COLL in the Vandenbergh-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 three corners twisted is a 'Sune case' (for the OLL usage).

Variants

  • The Sune is written as

  • Its inverse, the Anti-Sune (also known as Sune') is written as

  • An other variant is the Fat Sune, written as
Speedsolving Logo tiny.gif Alg r U R' U R U2 r'
  • The Fat Anti-Sune, written as

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.
