In cubing, "notation" refers to the system of symbols and letters used to describe moves on a cube. It allows cubers to follow along with "algorithms" (a sequence of moves that are required for switching specific pieces on a cube). Here’s an overview of the basic 2x2 notation:
Basic Notation
Face Turns
Each letter represents a face of the cube that should be turned:- R (Right)
- L (Left)
- U (Up)
- D (Down)
- F (Front)
- B (Back)
A letter without any additional symbols means a 90-degree clockwise turn of that face. A letter with an apostrophe (e.g., R') means a 90-degree counterclockwise turn. A letter followed by the number 2 (e.g., R2) means a 180-degree turn in either direction.
Notation Examples
- R U R' U': This notation represents a sequence of moves for algorithms commonly used in solving.
- R2 D2 F2: Each move here turns the respective face 180 degrees.
