The 3x3x3 cube pieces and notation

The pieces

To be able to solve the cube, we need to know it a bit, and to start, we will get to know the pieces of the cube. It has 26 pieces of 3 different types.

Centers

The cube has 6 centers, these are the pieces that only have 1 color. The centers never change position, they are always distributed in the same way.

Edges

The cube has 12 edges, these are the pieces that each have 2 different colors.

Corners

The cube has 8 corners. The corners have 3 different colors each.

3x3x3 cube notation

To be able to read and write series of moves, we use the notation that I will explain below.
The cube has 6 faces, and each face is assigned a different letter, which means turning the face 1/4 turn clockwise. Counterclockwise rotation is determined by placing a ' after the letter. If we need to turn a face 1/2 turn, we place a 2 after the letter.
  • F: Front - Front
  • U: Up - Up
  • D: Down - Down
  • R: Right - Right
  • L: Left - Left
  • B: Back - Back
Clockwise
Counterclockwise
The possible moves are as follows.

Side layers of the cube

Clockwise:
Counterclockwise:

Central layers of the cube

The middle layers also have an established notation, which is as follows.:

Two-layer moves

There are also two-layer rotation moves, represented by placing the letter in lowercase or adding a w after it. Here are 4 examples.:

Cube rotation moves

There is also notation indicating full cube rotations to change the face we are looking at. These are the following.:

Double moves

Double layer moves can be indicated by using the number 2 after the letter. The direction of the turn is not relevant, as whether done clockwise or counterclockwise, the result will be the same. Here are some examples.:
