What is the best formula for the fifth order Rubik s Cube to restore the four sides?

The fifth-order Rubik's Cube reduction formula is as follows:

Tools Ingredients: Fifth-Order Rubik's Cube.

1. The first step is to restore the center block (9 color blocks) of the six sides of the fifth-order Rubik's cube, and you need to restore the cross of 9 color blocks and then restore the four corner blocks, and the restoration of the cross is divided into 2 situations. When restoring the center cross, the center block is on two adjacent sides, you can use the formula tr u tr'Restore. The central block is on two opposite sides, using the formula tr2 b tr'2. Restoration; (The color blocks of the adjacent and opposite sides should be placed in the middle of the upper layer of that face).

2. After restoring the cross of the center block, the four corner blocks of the center block should be restored, which is divided into two situations: when the restored corner blocks are adjacent to the two faces, the formula tr u tr can be used' u tr u2 tr'Restore. When the corners of the restored corner are on two opposite sides, the formula tr2 b tr can be used'2 b tr2 b2 tr'2. Restoration; (The corner blocks of the adjacent and opposite faces should be placed in the lower right corner of that face).

3. In the second step, the edges of 12 faces are merged, and the two side edges of the edges need to be restored first, and then the middle edges need to be restored. When restoring two side edges, you need to turn the outer layer so that the side edges of the same color are on the left and right sides of the front. When the side edges are in the same second layer, the formula tu can be used' r f' u r'f tu makes the side edges on the same side.

When the side edge is located in the first.

For the second and fourth layers, you can use the formula ru' b'r2 to restore to the same layer.

4. Then restore the middle edge of the center block, rotate the outer layer, so that two side edges and one middle edge of the same color are placed on both sides in front of the top and back. When the top three colors are the same, you can use the formula tr2 b2 u2 tr2 u2 b2 tr2 to reduce the two side edges and the middle edge to one side.

5. When the three colors of the top surface are different, you can formula f r f' u f' u'f to revert to the same color.

6. When restoring the edge block group, the side edge and the middle edge may appear on the same side, but the color is different, the formula tr2 b2 u2 tl u2 tr can be used' u2 tr u2 f2 tr f2 tl'b2 tr2 to restore.

Fourth-order Rubik's Cube. The reduction mantra is as follows:

Up, right, down, right, backward, and left - swaps the positions of the small squares on the two adjacent vertices above.

Up, left, down, down, - swaps the positions of the small squares on the two diagonal vertices above.

Up, Left, Bottom, Left, Up, Left, Left, Left—The small squares on the three vertices above rotate 120 degrees.

Up, left, up, left, up, right, right, right - swap the small squares in the middle of the three edges in turn, and ensure that all the other small squares do not move, and all the formulas can ensure that the position and angle of the small squares below remain the same. You can start with one side of the Rubik's Cube and use this as the bottom.

Use the formula to adjust the position of the four small squares on the vertices above.

Use formula 3 to adjust the angles of the four small squares on the vertices above.

Use formula 4 to adjust the other small squares on the edge.

To restore the fourth-order Rubik's Cube, using 5 formulas, it is enough to restore the fourth-order solid color Rubik's Cube.

Merge heart block formula one: mrumr

Merge the center block, the above formula is just one way, according to the above formula, it can also be done in reverse, such as formula: ml'u'ml

When I first learned, I carefully understood the skills and rules of formulas, understood the meaning of formulas, and could restore them as I wanted without formulas.

Merge Prism Formula 2: MDRF'

After merging all the heart blocks and edge blocks, you can restore the fourth-order Rubik's Cube according to the third-order Rubik's Cube gameplay formula (the so-called reduced-order method restoration). Due to the characteristics of the fourth order, some special cases often arise in the end, which can be solved by the following two formulas.

Swap the two opposite edges.

Equation 3: mr2u2mr2

Straighten a group of edges.

Equation 4: MR2B2U2

Reduction method: that is, the fourth order is turned into a third-order to complete, the first shape, a center like the third order, there are four small color blocks, the second step is to adjust the edges to the same color, and the third step is to complete the six-sided way according to the third order.

Step 1: Form a center first.

Here is the international standard color to position, front red, back purple (or orange), upper yellow, lower white, left blue, right green, the completion of the step is to first complete the opposite side of the defeat of the center! For example, if you finish red first, you need to finish the purple (or orange) on the back

Step 2: Put all the edges together into a pair.

There are two main cases:

1. Spell two pairs of edges at a time.

2. When both edges are on the same side.

Please understand its process carefully, if you want to be fast, you must learn to put together two sets of edges at a time, and after being proficient, you can check the rubber size at a time, or even to six edges.

In fact, the fourth-order reduction principle is to turn it into a third-order! Then use the third-order method to restore! (However, because the fourth-order has no color center, the PLL is a little different from the third-order, and there are two more cases, so the third-order foundation + two fourth-order formulas can restore all the cases of the fourth-order).

Let me briefly talk about the steps, please read here for details.

1.Restore color centers. It's about putting the four small pieces in the middle together.

There is no formula for this, you have to play the rules by yourself, it's very simple, but pay attention to the color and don't spell it wrong! Very important! If you misspell it, you won't be able to restore it!

It is necessary to match the colors according to international standards: yellow on the top, white on the bottom, red on the front of the manuscript, orange on the back, blue on the left, green on the right).

2.Restore edges.

There are formulas here, just memorize one or two. (If this step is completed, it will become a third-order Rubik's cube, and then you will play according to the third-order.) If there are special cases, use the formula from step 3).

3.Special circumstances.

Formula:

MR refers to the right layer of the middle layer, which is the second layer from the right. MR is 90 degrees of clockwise rotation of the right layer, MR'It is counterclockwise on the right layer. MR2 is 180 degrees.

ML is the second layer from the left. ML is 90 degrees clockwise on the left layer'It is the counterclockwise of the left cover. ML2 is 180 degrees.

mu is the second layer from above. tu means that the upper two layers are rotated together. Tu2 is the upper two layers turned 180 degrees.

Structure. The fourth-order Rubik's Cube has a total of 8 corner blocks, 24 side blocks and 24 center blocks, and its composition is divided into two categories:

The center of the first type is a sphere, and each small piece around the perimeter is connected to the slide rail of the center ball, which slides in the direction of force when moving.

The second type is the fourth-order Rubik's cube with the axis as the core, which is very complex in composition, and has many additional parts in addition to the center ball and the surrounding blocks. As a racing sport, the fourth-order Rubik's Cube is the second type of movement, which is fast and not easy to get stuck in high-speed rotation.
