This PLL system is used to permute the last layer after orientation. Of the 21 cases, only 8 are needed for 2-Look PLL. Permutation is broken into 2 steps: corner permutation (four cases) and edge permutation (four cases).

- Step 1:
**Permutation of Corners**. Requires 4 algorithms to carry out (3 excluding mirrors):

- Step 2:
**Permutation of Edges**. Uses 4 algorithms (3 excluding mirrors):
