A commutator is a simple way to cycle around three pieces on a Rubik's cube. They are especially useful for blindfolded solving and FMC (Fewest Moves Challenge). So in this video, I will teach you how to recognise and execute a commutator.

Key points:
- A commutator cycles around three pieces.
- The interchange move is one move that can solve one of the pieces.
- Only two pieces can be affected by the interchange move.
- If all three pieces are in the interchange layer, do a move to take one piece out first. This is called a conjugate.
- Once you do the interchange, insert the third piece into the new location of the first piece.
- Commutator notation: [A, B] means A B A' B'.
