Since the double parity case above and the single dedge flip case both have a single dedge flipped, and since OLL algorithms do not necessarily aim to permute 4×44 the pieces that they correctly orient in any particular fashion, any 4x4x4 algorithm which solves:. OLL parity falls under this definition too so the reduced 4x4x4 has four times as many positions as you would expect.
A few of the slice turns can be wide to still just flip a single dedge, for example. The obvious example is PLL parity in 4x4x4: The remaining PLL parity cases which involve the fewest number of pieces besides the most popular case above are the following. Symmetrical algorithms are conjugates.

Two of the most popular 15 BHTM move algorithms which flip a single dedge on the 4x4x4 are the following. We can count that this algorithm has 7 block half turn parityy BHTM without breaking it up.
They also happen to be supercube safe. Since all OLL parity algorithms contain an odd number of 44×4 slice quarter turns, one can technically fix 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.
In fact, there has been debate 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 4x4x4 identifies as parity: Websites such as bigcubes. The shortest and well-known n x n x n cube odd parity fix which preserves the colors of the centers is r U2 4 r 13,9.
How to Solve a 4×4 Cube- The Rubik’s Revenge
Some algorithms may only be translatable to higher order even cubes 6x6x6, and larger. Below is an example algorithm found in December of Recalling that the term “2-cycle” is interchangeable with the common term “swap”, these cases perform 2 2-cycles of wing edges.
There are actually 58 of these cases in the last layer, in general. This page will keep strong focus on reduction parity OLL parity and PLL parity cases, but it will also include a limited number of other parity situations which are also common in other solving methods, as well as cases which share some characteristics with reduction parity algorithms.

It is also 4×44 not a speedsolving algorithm as “Lucas Parity” is. Reduction parity occurs when you try to reduce the puzzle so it can be solved by a constrained set of moves, putting it into some subset of the positions.
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. The 11,7 above discolors centers on, say, the 5x5x5 cube.
The most popular 2-cycle a swap of two pieces besides the single dedge flip case is the following. Here’s one video tutorial that illustrates the typical process.
However, many who solve the 5x5x5 Rubik’s cube using some variant of the Reduction Method will come across this case; and thus several but not all of the algorithms listed on this page which solve this case directly can be used for completing the tredge-tripling stage of a 5x5x5 Reduction solve.
At the same time, we can count a total of 11 block quarter turn moves BQTM. Clearly this algorithm has much more of a variety of moves than “Lucas Pparity. Algorithms with fewer BHTM are listed first in each category. We can break up this algorithm as f f r E E r E E r f pqrity to count 4 f’s and 3 r’s.
Despite that one can technically solve all 22 PLL parity cases by executing an algorithm meant to solve any one of them to any face and then finish solving the 4x4x4 as if it was a 3x3x3, special algorithms have been developed for every case. Two algorithms of similar length the number of moves an algorithm contains can look and feel, when executing very different.
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.
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 addition to the fact that all parity cases on this paroty are each represented by 4x4c4 case image, The number of moves an algorithm contains in these two big cube pairty metrics is written next to them in the form of the ordered pair, BQTM, BHTM.
Should one wish to induce an odd permutation in the wing edges of the 4x4x4 with a short algorithm without having to restore the cube as much as applying an inner slice quarter turn requires, below are fairly short ;arity simple algorithms one can use. This was deduced from the same idea that Floyd Newberry came up with for using a short repeated sequence to directly solve a 2-cycle.
