Learn how to solve the 4x4x4 Rubik’s Revenge Cube easily. the 4×4 Rubik’s revenge is very similar to it and requires only few more algorithms to learn. The You CAN Do the Rubiks Cube Program objective is to share the secrets of solving the Rubiks Cube with youth and to also encourage them to help others to . This page attempts to list move optimal algorithms for every common form of parity encountered in popular 4x4x4 (Rubik’s Revenge) solving.
Since all OLL parity algorithms contain an odd number of inner slice quarter turns, one can technically 4s4x4 any 4x4x4 wing edge odd parity case by executing a single slice quarter turn and then resolve the cube using an even number of inner slice quarter turns. The most popular 2-cycle a swap of two pieces besides zlgorithms single dedge flip case is the following.
Algorithms with fewer BHTM are listed first in each category. However, the other 54 will only be encountered during a K4 Method solve. The remaining PLL parity cases which involve the fewest number of pieces besides the most popular case 4x44x4 are the following. Besides containing case images and algorithms for reduction parity cases, this page also contains odd parity cases which can technically be used to pair dedges, since they permute wing edges in a manner which separates wing edges in the same dedge from each other.
The term “parity” can be used to describe a number of situations that occur during a 4x4x4 solve which cannot manifest during a 3x3x3 standard size Rubik’s cube solve. Which face of the cube is not important because all we are doing in this section is matching the same coloured edges. Combining some form of PLL parity and a single dedge flip creates one of the many cases of what’s commonly called double parity.
Ensure the front face colours match. The aim of this section is to take you from this. Algorithms for the Cage Methodas well as algorithms for theoretical purposes and general 4x4x4 exploration are present as well. Although symmetrical algorithms are technically conjugates of non-symmetrical algorithms, non-symmetrical algorithms are algorithms which are solely the result of a composition of one or more separate algorithm pieces, which all together accomplish the desired task.
This page not only contains commonly practiced speedsolving algorithms: You can safely rotate any face to create a starting configuration. For example, aalgorithms of the most common single parity algorithms used by 4x44x4 speedcubing community is “Lucas Parity”.
We can clearly see this in the above algorithm bar. One can split up r2 as r r or as r’ r’ and insert 3x3x3 moves to obtain the pure form of PLL parity. A clear example of a symmetrical algorithm is Stefan Pochmann’s n x n x n opposite PLL parity algorithm, Rw2 F2 U2 r2 U2 F2 Rw2where all moves in the algorithm are conjugate moves except for the one move in the middle.
That is, besides just showing parity cases and algorithms for those cases, this page attempts to attribute credit to the original founder of an algorithm as well. In fact, the most popular speedcubing single parity algorithms perform additional swaps besides flipping a single dedge due to the use of wide turns. In fact, there has been 4x44x4 about what situations are considered to be a parity casebut there is one situation of which any cuber who uses the term “parity” for the algoritjms identifies as 4x44x Although this algorithm is not listed under a case image on this page, it would appear in the following format in an “algorithm bar” if it was.
How to solve a 4×4 Rubik’s Cube
No “conjugate assistance” is used. It is common convention among the speedcubing community to use algorithms which contain wide double layer turns to solve OLL parity instead of single inner layer slices.
In each case an incorrectly positioned pair of edges must be at the top of the front face alglrithms a correctly positioned pair at the top of right face.
This PDF includes all 58 cases and short algorithms to solve each one. Such an algorithm is called a non-pure algorithm when compared to algorithms which just flip a single dedge, which are often called pure flips.
4x4x4 parity algorithms
At the same time, we can count a total of 11 block quarter turn moves BQTM. On January 24,speedsolving.
The “w” is short for “wide”. This allows one to use fewer moves to solve any given case and gives one more options.
4x4x4 Disparity Algorithms
Finally, one of the simplest OLL parity more specifically, a double parity algorithms found in December of to remember also consists of a short repeated sequence:. You need to place a matching colour pair on different layers but on the same face of the cube in the configuration displayed here on the alyorithms. Algorithm names alglrithms be explained next. Solutions listed under a case image which are not move optimal in the move metric in which algorithms are sorted by:.
Some algorithms may only be translatable to higher order even cubes 6x6x6, and larger. Although the third column 4s4x4 the majority of the algorithm bars on this page is blank, when it is not blank, it is either an algorithm name given by the algorithm author or an algorithm label for organizational or classification purposes.
The four cases above clearly switch two dedgesbut they can also be interpreted as doing two separate swaps of wing edges. Wiki tools Special pages. This 2-cycle of wings is as common during algorihms K4 Method solve as the single dedge flip is, but it should never arise during a solve using the Reduction Method because two dedges are not paired up.
For example, performing a swap of dedges to a fully solved 4x4x4 and then flipping the front dedge resulting from that swap gives us the following.
OLL parity falls under this definition too so the reduced 4x4x4 has four times as many positions as you would expect.
When you still have to solve the last two edge elements you do not 4x4c4 a third set to reset the centres with. It’s worthy to note that the majority of algorithms in this section, like the 25,15 solutions, were found by using the 3x3x3 Classic Setup in Cube Explorer.
