What is the formula for spelling a Rubik's cube?

1, the formula of right-handed fish is: rur' uru2r';

2. The formula of left-handed fish is: L'U'LU'L'U'2L:

Formulas in Rubik's cube reduction often use URLF instead of Rubik's cube reduction steps:

U indicates that the top surface of the Rubik's cube, that is, the top surface of the Rubik's cube rotates 90 degrees clockwise;

R stands for right, that is, the right side of the Rubik's cube, that is to say, the right side of the Rubik's cube rotates 90 degrees clockwise;

L means left, which means the left side of the Rubik's cube, that is to say, the left side of the Rubik's cube rotates 90 degrees clockwise;

F stands for front, which means the front of the Rubik's cube, that is, the front of the Rubik's cube rotates 90 degrees clockwise.

Extended data:

The variable principle of the third-order Rubik's Cube is as follows:

8 corner blocks: interchangeable positions (8! ), you can also flip the direction (38? ), but you can't flip a corner block alone (1/3), so there are 8! × 37? This change.

12 block: interchangeable position (12! ), you can also flip the direction (2 12? ), but it is impossible to exchange a pair of ribs (1/2) and turn a rib alone (1/2), so there is 12! × 2 12? /(2 × 2) variation.

6 center pulleys: fixed and immovable.
