If anybody can tell me what JPERM does when he test out a cube? I know he does a J-PERM and an R-PERM but then he does this weird alg that has D moves that solves the R-PERM that he does and I want to know what it is, you can see it through this link on when he is testing out the qiyi MP lineup on the 3x3:
please and thank you!
