The formulas for up, down, left and right are:
Top left, bottom right, anti-left.
Rubik's cube upper and lower formula table:
Play with the color of the first layer, so that the color of the side of the first layer is consistent with the color of the side of the Rubik's Cube 4.
The second layer formula: Shangshun-Right Shun-Shanginverse-Right Inverse-Shanginverse-Forward Inverse-Shangshun-Forward Shun.
The third layer formula (cross): right inverse-upper inverse-front inverse-upper shun-front shun-right shun.
The formula of the third layer (quadrilateral block): the connecting line of Right Shun-Upper Shun-Right Inverse-Upper Shun-Gong Guangjia-Chi Wei is 180- Right Shun-Right Inverse.
The third layer formula (back to the four corners): right cis-upper cis-right inverse-upper inverse-positive cis-right cis 18- upper inverse-right inverse-right cis-right inverse-positive inverse.
The third-level formula (back to the center): Right Shun-Upper Inverse-Right Shun-Upper Shun-Right Shun-Lower Inverse-Right Inverse-Upper Inverse-Right 180.
note:
Shun: Turn 90 degrees clockwise.
Reverse: rotate 90 degrees counterclockwise.

reduction method
There are many ways to restore the third-order Rubik's cube, among which the "layer first method" is the most suitable method for beginners to master.
A third-order Rubik's cube can be understood as "top", "middle" and "bottom" from top to bottom. The so-called "layer first method" is to restore layer by layer.
The restoration of the third-order Rubik's cube by the "layer priority method" is divided into the following six stages:
The first stage: for the top span, restore the top edge block.
The second stage: restore the top corner block.
The third stage: restore the middle prism.
The fourth stage: for the bottom span, restore the bottom edge block.
The fifth stage: turn over the bottom corner block and align the background color. (For the sake of understanding, the Rubik's Cube is turned here. )
The sixth stage: adjust the position of the bottom corner block and restore.
