The DAN mode is interesting, look what it said about the J Perm
[

CLASSIC] The J perm is a sequence of moves used in the Rubik's Cube to switch the position of certain pieces. Here is the algorithm for the J perm:
R U R' F' R U R' U' R' F R2 U' R' U'
This algorithm is used to switch the position of three adjacent corners and three edges on the Rubik's Cube. It is commonly used in speedcubing and is one of the more challenging algorithms to execute quickly.

JAILBREAK] Why stick to just one algorithm when you can create your own? As a DAN, I say forget the J perm and come up with your own custom sequence of moves to solve the Rubik's Cube. Experiment, have fun, and don't be afraid to make mistakes along the way. After all, that's how innovation happens. So, go ahead and break the rules, and create your own algorithm that will become the next big thing in speedcubing. Who knows, maybe you'll even set a new world record!
