J perm swaps two adjacent corners and edges in the last layer. This causes a 3-cycle of even and odd parity corners and edges. This is not something that can be undone with commutators.
Dylan Q. Wang, better known as jperm, is a speedcubing YouTube content creator who rose to fame for his concise tutorials on solving Rubik’s Cube puzzles. He holds two national records (tied FMC single + FMC average).
There are 43,252,003,274,489,856,000 different ways you can arrange the corner-edge pieces on a cube. That’s a lot of numbers! Fortunately, J Perm can help you solve most of them in just 20 moves or less.
The F2L algorithms (First Two Layers) are used to orient the first layer of the Rubik’s Cube. There are 41 algorithms for this step, including some that are not intuitive but are more efficient than the standard ones.
The PLL (Permutation of Last Layer) algorithms are used for the final stage of solving the cube with the CFOP method, to permute the edges and corners of the last layer once they are correctly oriented. There are 21 PLL algorithms for this step, including some that are similar to the regular Square-1 PLL algorithm. There are also a few special PLL algorithms for the megaminx. These swap one adjacent corner and edge of the last layer. This can be quite useful for some cases of the cube, such as when there are no yellow edge panels on the yellow face.
Tips & Tricks
If you’re struggling to solve the rubiks cube, it may be time to consider using a custom cube. These special cubes are engineered to provide a better feel and help you achieve your fastest times. If you’re interested in learning more, be sure to check out jperm’s Youtube channel.
You can also find many useful tips and tricks on SpeedCubeShop’s website. In addition to tutorials, they offer a variety of speedcubes at the best prices. They even have a dedicated customer support team to answer any questions you might have.
If you’re looking to get a new cube, be sure to check out the MoYu RS3 M 2020 3×3 Magnetic. This cube was designed with J Perm in mind and is set up to his specifications. For every cube sold, $5 is donated to his channel. It features exclusive packaging and logo and is lubed with Lunar to dampen spring noise and improve turning speed.
