Basic Turns To start, you'll want to be familiar with the basic notation from the SpeedSolving wiki. If the turn does NOT include the shallowest layer, on the other hand, we include both numbers and put a - between them. So, on the 4x4x4 cube, the four horizontal layers can be described as U , 2U , 3U , and 4U.

Fi means front inverted. Basically, you have the same letters of the 3x3 U R F B L D , upper-case if referring to external layers, lower-case if referring to internal layers.

You ask: People have suggested a many extensions to the standard notation. For suffixes, we simply do the same thing we do in parenthesized groups: Less Common Extensions People have suggested a many extensions to the standard notation. A letter with the number 2 after it marks a double turn 180 degrees: Just make sure to explain them.

Thus, the turns including the shallowest layer are labeled u , 3u , 4u , and so on. There is an official scramble notation for WCA competitions which has continued to change over the years , which uses Rw as Rr , 3Rw as l' r R , and so forth.

One potential problem is that it is important to keep spaces between adjacent turns in SiGN, because otherwise there are situations that could be interpreted as two or more totally different things. For rotations of the entire cube, SiGN uses the common and traditional notation from the 3x3x3 cube.

To solve OLL parity I could use the following algorithm: What is the official notation to 4x4 movements if any exists? It'd be inconvenient to switch, but we certainly could.

F R' U2. For single-layer turns, we add the number of the layer, starting from 1 for the shallowest layer on one side and going up as the layers go deeper. It is just a matter of those sites to make it visible what notation they are using.

Suppose that P and Q represent two sequences of moves they don't have to be enclosed in parentheses. These extensions are used to make sequences smaller and more easily understood, and all of the ones in this section are common enough for most serious cubers to follow.

That is the one i was expecting: It's also complete enough to describe both multiple- and single-layer turns as one step, mirroring the way cubes behave in real life.

However, this site uses the notation Rr to define "both layers" My question: The notation used can change depending on who's doing the notating, and this is true of all higher-dimensional puzzles.
