2-Look PLL
From Speedsolving.com Wiki
This PLL system is used to permute the last layer after orientation. Of the 21 cases, only 7 are needed for 2-Look PLL. Permutation is broken into 2 steps: corner permutation (three cases), and edge permutation (four cases).
- Step 1: Permutation of Corners. Requires 2 algorithms , to carry out:
- Step 2: Permutation of Edges. Uses 4 algorithms (3 excluding mirrors):
