x y z: whole cube rotation
Adding [T]: turning two layers of the corresponding side
Adding [M]: turning the internal layer of the corresponding side
Adding [‘]: 90 degree turn counter clockwise
Adding : 180 degree turn clockwise
Adding [‘2]: 180 degree turn counter clockwise
In this tutorial we will introduce the ‘Reduction method’ which will require us to first solve the center pieces and turn the edge pieces to form an equivalent to the 3x3x3 cube. Then we will be able quickly solve the cube using the methods for solving the 3x3x3 cube.
Solve the center
pieces of all 6 sides
Pair the edge pieces
Apply 3x3x3 methods
&deal with parities
Solve the center piecesby aligning the 4 center pieces of each colour and positioning them in the orders
For big cubes with even number of layers, the center pieces are not fixed on certain sides You need to memorize the relative positions of the different colours. In the case of GAN460 this is top-yellow, down-white, left-orange, rlght-red, fronC-blue, back-green.
Turn the edge piecesto pair them up

If the last 2 edge pairs can not be solved, apply algorithm 4.
Solve the cube like the 3x3x3 cube, and deal with parities.
Now your 4x4x4 cube should look like a 3x3x3 cube. Use the 3x3x3 methods to solve it until you encounter a parity case.
In case of parity situations, use the algorithms below
Two scenarios as shown below might happen when making the
cross on the top side. Use algorithm 5 to handle it
Algorithm5 TR U2 x TR U2 TR U2′ TR’ U2 TL U2 TR’ U2′ TR U2 TR’ U2′ TR
When solving the top face, if you entcounter the scenario can
not be solved, apply algorithm 6 once where 2 opposite edges to solve it.
