Two algorithms of similar length the number of moves an algorithm contains can look and feel, when algoriyhms very different. There are links to either forum posts or video URLs in the right-most column of many “algorithm bars”. The most popular 2-cycle a swap of two pieces besides the single dedge flip case is the following. Note that with many algorithms, it’s not “all or nothing”.

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.

An equally well-known form of reduction parity this term will be defined formally soon besides the single dedge flip is switching two opposite dedges in the same face. The first part of this process, as with the centres, is more about seeing what is happening rather than learning algorithms. This page will keep strong focus on reduction parity Algorirhms 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 algoriithms reduction parity algorithms.

### How to speedsolve the 4x4x4 cube – Solving the 3x3x3

All algorithms can be applied to the 6x6x6 if instead of turning the outer 2 layers, turn the outer 3 layers; instead of turning 1 inner layer slice, turn 2 inner layer slices.

Most of the algorithms on this page affect some centers of the 4x4x4 supercube: Recalling that the term “2-cycle” is interchangeable with the common term “swap”, these cases perform 2 2-cycles of wing edges.

The 11,7 above discolors centers on, say, the 5x5x5 cube. Solutions listed under a case image which are not move optimal in the move metric in which algorithms are sorted by:. Ensure the front face colours match. You will notice that the pair are matched after the first rotation in the algorithm, however, the four centres on the side faces have now been split, the rest of the algorithm places the newly matched pair on the up face then replaces them with the split pair which are turned to the front face so the side face centres can be realigned.

Although the third column in 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.

A few of the slice turns can be wide to still just flip a single dedge, for example. Naturally, these type of parity cases are called reduction parity. The shortest 4x4x4 cube odd parity fix which preserves the colors of the centers essentially independently found in by Tom Rokicki and Ed Trice is f2 r E2 r E2 r f2 11,7. However, the term pure is more formally associated with algorihhms algorithm being supercube safe –algorithms algorith,s do not permute move any centers in the supercube version of a given order.

However, the other 54 will only be encountered during a K4 Method solve. There is actually a total of last layer 4-cycles, but since 4-cycles in two dedges are the only 4x4x encountered using the most popular 4x4x4 solving methods, they are the only ones algorithmd on this page. Similar to doing an inner slice quarter turn like r algorithma technically fix the single dedge flip parity, an inner slice half turn such as r2 is technically all that is needed to fix PLL parity.

Pairing the Edges The first part of this process, as with the centres, is more about seeing what is happening rather than learning algorithms. The following 21 slice quarter turn algorithm was the only 21 slice quarter turn 3x3x3 algorithm which was closest to being a single dedge flip algorithm. 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 algoirthms for algoriithms 4x4x4 identifies as parity: That is, there is a total of 22 PLL parity cases.

This algorithm solves the cube for Fig. 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. For example, the second 15 BHTM algorithm mentioned above could be expressed later on this page with the following algorithm bar, since all of its inner slice turns can be made wide hence the “Y” instead of an “N” and its first and last moves 4c4x4 be wide and still solve the pure dedge flip case hence why the algorithm begins and ends with Rw2 instead of r2.

## How to solve a 4×4 Rubik’s Cube

In MayMichael Gottlieb defined reduction parity in detail. Symmetrical algorithms are conjugates. Perhaps if the 3x3x3 Classic Setup is used up to depth 21, some 21 slice quarter turn solutions may be found.

U2 r2 U2 r2 Uw2 r2 Uw2. Which face of the cube is not important because algorithmd we are doing in this section is matching the same coloured edges.

If not, Right clock, Top anti, Back clock. More will be explained about what other pieces of information in the algorithm bar above mean later. In practice, human creation of symmetrical algorithms requires more trial and algorith,s of algoruthms paths in both creation of the base the base is defined as the move sequence B in A B A’ and final setup moves, whereas the creation of non-symmetrical algorithms requires having knowledge of forming different pieces individually and knowing how to combine them.

In fact, the most popular speedcubing single parity algorithms perform additional swaps besides flipping a single dedge due to the use of wide turns.

We can clearly see this in the above algorithm bar. Should one wish to induce an odd permutation in the wing edges akgorithms 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 and simple algorithms one can use.

## 4x4x4 parity algorithms

A clear example of a symmetrical algorithm is Stefan Pochmann’s n x n x n opposite PLL parity algorithm, Algoritthms F2 U2 r2 U2 F2 Rw2where all moves in the algorithm are conjugate moves except for the one move in the middle.

For example, one of the most common single parity algorithms used by the speedcubing community is “Lucas Parity”. However, despite that all 25,15 single dedge flip solutions which begin and end with an l2 or r2 move can instead be Lw2 and Rw2, respectively, all slices will be expressed as single slice lowercase turns for simplicity for all 25,15 solutions.
