# Commutator and J Perm Speedcubing

A commutator is a mathematical object with a certain pattern. This pattern is called ABA’B’. Each move sequence in a commutator contains an even number of quarter turns. These quarter turns change the edge and corner permutation parities. A Jperm, on the other hand, requires an odd number of quarter turns.

## Solve f2l in 5 seconds

There are two basic strategies to speedcubing. The first one involves solving the first two layers of the puzzle. The second strategy involves solving the cross. In both strategies, you need to use a stackmat timer. In addition, the time taken to pick up the cube counts towards the total time and can affect your cross solution. It is important to practice the F2L puzzles on a stackmat before trying to solve them in competition.

The first strategy is to practice solving F2L pairs blindfolded. The purpose of this technique is to develop your lookahead ability, but without making any mistakes or beat misses. The hardest part of this drill is the transition between the first pair and the cross. The transition from one pair to another requires a great deal of lookahead.

The second strategy is to improve your F2L. While this may seem complicated at first, it requires more practice. The key is to learn to recognize and track several pieces at once, allowing yourself to have more freedom. Practice will help you improve your speedsolving technique, but memorizing a number of F2L cases is a slow way to learn the formula. Start by practicing until the F2L becomes instinctual. There are many steps to a basic F2L. Some of these steps can be combined to make it easier.

Permutation of the Last Layer (PLL) is another method used for speedcubing. This technique rearranges all of the pieces in the last layer. It requires y algorithms total. It is usually slower, but it is faster than the traditional beginner method.

## Commutator moves sequences

A commutator is a move sequence containing two pieces whose pairs are the same. These two pieces are always the smallest in the puzzle. A commutator moves sequence is usually performed with two hands. A one-handed commutator will be slower than a two-handed one.

This move is also called the J-perm because it swaps adjacent corners and edges. The first move rotates the board one-quarter turn, while the second move rotates the board a fourth turn. It is possible to speed up the commutator moves sequence with tools.

A commutator is a simple way to build sequences of moves. It orients and permutes the pieces, and can be used to solve any three-cycle cube variant. To use a commutator, the cube must have two pieces in the same level. The third piece, however, cannot be in the reference level. A commutator can be used on any three-cycle cube, but it must be the obvious same kind.

Commutator moves are sequences of moves that influence a few pieces in the puzzle. Each commutator contains a commutator pattern, which is usually X Y X’ Y’. Commutators are also used to create inverse sequences.

## J-perm method

The J-perm speedcubing method uses a special move sequence that is optimised for speed. The moves are shorter and have less structure than longer sequences. The moves are performed by alternating two adjacent edges and corners. Then, one of them is returned to its original position.
