2-Look PLL

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:
  1. adjacent corner swap (A-perm)
  2. diagonal corner swap (any of Y-Perm, V-Perm, E-Perm, N-Perm)

• Step 2: Permutation of Edges. Uses 4 algorithms (3 excluding mirrors):
  1. clockwise 3-edge cycle (U-perm a)
  2. anticlockwise 3-edge cycle (U-perm b)
  3. opposite edges swap (H-Perm)
  4. adjacent edges swap (Z-Perm)

Edge Permutation Cases

• H Permutation
• U Permutation (CCW)
• U Permutation (CW)
• Z Permutation
