0 1. Up, right, down, right and inverse left-switch the positions of small squares on two adjacent vertices above?

02. Up, left, down and down-exchange the positions of the small squares on the two diagonal vertices above?

03. Top left, bottom left, top left, Zuo Zuo and bottom Zuo Zuo-the small squares on the top three vertices are rotated 120 degrees.

04. Up, left, left, right, bottom, right, bottom and right-exchange the small squares in the middle of the three edges in turn, while ensuring everything else.

The small square does not move.

All formulas can ensure that the position and angle of the small square below remain unchanged.

You can first face the side of the Rubik's cube and use it as the bottom.

0 1. Adjust the positions of the four small squares on the vertex with the formula 1 2?

02. Adjust the angles of the four small squares on the top vertex with formula 3?

03. Adjust other small squares on the edge with formula 4.

Extended data:

The third-order Rubik's Cube is the most common Rubik's Cube at present, which was invented by Professor Ern Rubik of Budapest Institute of Architecture in 1974.

The English official name of the third-order Rubik's Cube is Rubik's? Cube, whose English name is named after Professor Ern Rubik.

At the beginning, he invented the Rubik's Cube only as a teaching tool to help students enhance their spatial thinking ability. But it is not only a mechanical problem to make those small squares rotate at will without scattering, which involves the wooden axis, seat and tenon.

It was not until the Rubik's Cube was in his hand that he turned the Rubik's Cube several times that he found that how to restore the chaotic color squares was actually an interesting and difficult problem. Rubik is determined to mass-produce this kind of toy. The Rubik's Cube swept the world soon after it was invented.
