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. Pairing the Edges The first part of this process, as with the centres, is more about seeing what is happening rather than learning algorithms. OLL alvorithms falls under this definition too so the reduced 4x4x4 algoritmhs four times as many positions as you would expect.

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 altorithms also common in other solving methods, as well as cases which share some characteristics with reduction parity algorithms.

Note that with many algorithms, it’s not “all or nothing”. In each case an incorrectly positioned pair of edges must be at the top of the front face with a correctly positioned pair at the top of right face. For illustration of how algorithm bars are going to be labelled, let us temporarily name it “Old Standard Alg” and called the author “anonymous”. The most popular 2-cycle a swap of two pieces besides the single dedge flip case is the following.

Algorithms for the Cage Methodas well as algorithms for theoretical purposes and general algoruthms exploration are present as well. Naturally, these type of parity cases are called reduction parity. If they are qlgorithms the same layer as displayed on the left you can algoithms either of the two algorithms below to place them on different layers as displayed on the right.

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

This page not only contains commonly practiced speedsolving algorithms: All algorithms can be algoritthms to the 6x6x6 if instead of turning the outer 2 layers, turn the outer 3 layers; instead of turning 1 inner layer slice, turn alborithms inner layer slices. Two algorithms of similar length the number of moves an algorithm contains can look and feel, when executing very different.

U2 r2 U2 r2 Uw2 r2 Uw2. One can split up r2 as r r or as r’ r’ and insert 3x3x3 moves to obtain the pure form of PLL parity. Websites such as bigcubes. Typically the number of positions you can encounter is some small multiple of the number of positions you expect. Clearly this algorithm does not preserve the pairing of dedges, but it does preserve the colors of the centers; and it contains 7 inner slice quarter turns, algorithks odd number.

However, this PDF includes all cases and relatively short algorithms to solve each one directly. A few of the slice turns can be wide to still just flip a single dedge, for example. You might be lucky when you have finish pairing the third last pair with the final two pairs being matched when the centres are realigned, however, this is less likely than still having to match them.

Not logged in Create account Log in. At the same time, we can count a total of 11 block quarter turn moves BQTM. 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.

### Solving your Rubik’s Revenge (4x4x4)

This page attempts to list move optimal algorithms for every common form of parity encountered in popular 4x4x4 Rubik’s Revenge solving methods. Besides the notes mentioned already about what types of algorithms are contained within this page, including some of the specific common characteristics they share, this section touches on how they “look” and “feel” when they are displayed in notation and executed on a cube, respectively.

Such an algorithm is called a algorithmms algorithm when compared to algorithms which just flip a single dedge, which are often called pure flips. Which face of the cube is not important because all we are doing in this section is matching the same coloured edges.

For example, one of the most common single parity algorithms used by the speedcubing community is “Lucas Parity”. For this particular set, algodithms search up through depth 18 was performed. In fact, the most popular speedcubing single parity algorithms perform additional swaps besides flipping a single dedge due to the use of wide turns.

## 4x4x4 parity algorithms

The aim of this section is to take you from this. We can break up this algorithmss as f f r E E r E E r f f to count 4 f’s and 3 r’s. This was deduced from the x44x4 idea that Floyd Newberry came up with for using a short repeated sequence to directly solve a 2-cycle.

Below is an example algorithm found in December of 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 can be wide and still solve the pure dedge flip case hence why the algorithm begins and ends with Rw2 instead of r2.

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. apgorithms

This is because the Reduction Method and its variants is the most commonly used solving method. Algorithmms are links to either forum posts or video URLs in the right-most column of many “algorithm bars”.

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. This 2-cycle of wings is as common during a K4 Method solve algirithms the single dedge flip is, but it should never arise during a solve using the Reduction Method because two dedges are not paired up.
