How many levels does the Rubik's Cube have?
Pocket cube
The English official name of the second-order Rubik's Cube is PocketRubik's Cube or Mini Cube, and the Chinese literal translation is Pocket Rubik's Cube. It has two squares on each side. One official version of the Rubik's Cube has a side length of 40 mm, and the other axial second-order Rubik's Cube developed by Dong Xian has a side length of 50 mm ... The total variation of the second-order Rubik's Cube is 3,674, 160 or about 3.67× 10 6. Pocket cube, also known as pocket cube, mini cube, small cube and ice cube, has a cube structure of 2×2×2. There are only eight corner blocks in itself, and there are no squares with other structures. The structure is similar to the third-order Rubik's cube, because it has no central block, so it can be restored by the open-minded method and the formula of restoring the third-order Rubik's cube.

Rubik's Cube
The English official name of the third-order Rubik'sCube is Rubik's Cube, named after Professor Rubik. It is the most common Rubik's cube at present. It has three squares on each side, the side length of the official version of the Rubik's Cube is 57 mm, and the total variation of the third-order Rubik's Cube is (8! x3^8x 12！ X2 12)/(2x2x3) = 43, 252, 003, 274, 489, 856, 000 or about 4.3x10/9+09. The third-order cube is connected by a central axis with six central blocks and eight corners. The third-order Rubik's cube is the most common in life, but in March of 20 1 1, a new third-order bread cube appeared, which broke the conventional cube design of the third-order Rubik's cube.
Rubik's revenge
rubik's revenge
The English official name is Rubik'sRevenge, which literally translates as "Revenge of the Rubik's Cube". Compared with the third order, it is much more complicated, and its composition is divided into two categories. One is that the center is a sphere, and each peripheral small block is connected with the slide rail of the center ball, and will slide on the slide rail along the stress direction when moving. The second is the fourth-order Rubik's cube with the axis as the core. This fourth-order Rubik's Cube is actually a fifth-order Rubik's Cube that hides the middle layer. The small parts inside are the fifth-order side center block and the middle side block, and there are protruding devices on the central shaft to prevent locking. As a racing sport, the fourth-order Rubik's cube with the second structure moves fast and is not easy to get stuck in high-speed rotation. The side length of the fourth-order Rubik's Cube official version is about 67mm, and that of the Mayfords version is 60mm. The fourth-order Rubik's cube is considered to be the most difficult to restore among the second-order and fifth-order Rubik's cubes. Although there are more varieties of the fifth-order Rubik's cube than the fourth-order, the central block of the fourth-order Rubik's cube is not fixed and cannot be restored by ordinary methods. The fourth-order Rubik's Cube * * has 7401196841564901869874093949857360000.
Professor's cube
The English name of the fifth-order Rubik's Cube is called Professor'sCube, which literally translates as "Expert's Rubik's Cube". There have been three kinds of five-order Rubik's Cube in the world, namely M5 in Dong Xian, China, R5 in Rubik's Cube and V5 in Greek Olympics. It takes a long time to invent a new high-order Rubik's cube, because we should not only consider the feasibility of the project, but also consider whether the Rubik's cube can be used stably for rotation after it is made. It is for this reason that the fifth-order Rubik's Cube is the highest-order Rubik's Cube officially announced, and its structure is beyond the imagination of ordinary enthusiasts.
The fifth-order Rubik's cube is more difficult. The fifth-order Rubik's Cube and the fifth-order Rubik's Cube always have 8 corner blocks, 72 side blocks (two types) and 54 center blocks (48 movable blocks and 6 fixed blocks). The central block of the fifth-order Rubik's Cube is 3×3 structure, so four central blocks of each color are equivalent, that is, the change state of the central block is (24! (4! 6))2 kinds. The positions of its 24 outer blocks cannot be moved at will, so there are always 24! A constantly changing state. 12 The 1 1 of the central side block can be interchanged, so the total * * * is 12! /2×2 1 1 Change the state. The total number of states of the fifth-order Rubik's Cube is 2828709422774 1, 8565318033310715032829365438+.

The sixth-order Rubik's Cube is produced by the Greek Olympic Rubik's Cube Company. The corners are slightly larger than the central block, and the edges are slightly rectangular. The evaluation of the Rubik's cube itself is not very good. The common evaluation is easy POP: it refers to the situation that some parts of the Rubik's cube are separated from the Rubik's cube when it is restored. If it appears in the competition, it will be regarded as an invalid recovery process. In order to prevent lock-up, there is a click device inside the box, but it also seriously affects the feel. Turn up one card at a time. Magic friends usually carry out a series of polishing and transformation, which can greatly reduce frustration and reduce many opportunities for pop.

The eighth-order Rubik's Cube was made by the magic friend of the Rubik's Cube Bar, the big cigarette butt (the fourth-order R structure was changed from the blue seventh order to the eighth order). Although the eighth order is lower than the ninth order, the result is more complicated than the ninth order.

Good anti-pop ability, not easy to fall apart; The middle shaft is made of high-grade nylon material; Fault tolerance is the deviation of one square in a small square, which can be done by L'R' action.
12 Rubik's Cube was made by the magic friend "Leslie" and released in foreign forums such as TP, but not in domestic forums, so many magic friends didn't know it, and the producer himself didn't show the intention of becoming famous, so it was relatively low-key.
