Cube Notation is letters and letter character combinations to describe specific turns on a 4x4 . The purpose of notation is to easily describe an algorithm or a scramble.  

Uppercase letters describe one 90 degree turn of one layer the letter represents.

If the letter is followed by an apostrophe then the turn is anti-clockwise.



- UP -

Capital Letter U is only the top payer


Lowercase u is the inner top layer

4x4 notation inner up

Capital U followed by lowercase w is both the top and inner top layer together

4x4 Notation 2 layers up


The concept above applies to the Right, Left, Back, Front and Down layers.
