## PBL

These are the cases to permute the corners in both layers. There are only a few cases to learn here and you probably already know a few of them.

Name | Diagram | Algorithm | Comments |

T | (R U R' U') (R' F) (R2 U') (R' U' R U) (R' F') |
I use the T-perm 3x3 alg. You could alternatively use the J-perm or A-perm alg. | |

T | x2 (R U R' U') (R' F) (R2 U') (R' U' R U) (R' F') |
Just rotate to put the solved layer on the bottom and do a Y-permutation. | |

Y | (F R U') (R' U' R U) (R' F') (R U R' U') (R' F R F') |
I use the Y-perm 3x3 alg. You could alternatively use the N-perm alg. | |

Y | z2y (F R U') (R' U' R U) (R' F') (R U R' U') (R' F R F') |
Just rotate to put the solved layer on the bottom and do a Y-permutation. | |

UF/DF | (R2 U' R2') (U2' y) (R2 U' R2') |
Rotate in the direction of y as you perform the U2'. | |

U adj D diag |
(R U' R) F2 (R' U R') |
If you have D2 of this case, you can mirror it. | |

U diag D adj |
(L D' L) F2 (L' D L') |
If you have U2 of this case, you can mirror it. You could also perform z2 and do the alg above. | |

UD diag | R2 F2 R2 |
Rejoice. This is the nicest case. |
