2×2 CLL Pi algorithms
The Pi group has 6 of the 42 2×2 CLL cases: P1, P2, P3, P4, P5, P6. See all 2×2 CLL · other groups: Sune (6) · Antisune (6) · T (6) · U (6) · L (6) · H (4).
Recognizing 2×2 CLL Pi
No yellow corners on top; one side has yellow headlights, the other 2 yellow stickers face away from each other.
Cases in the group differ by the side stickers of the 4 corners: look for headlights (two matching stickers side by side) or opposite colors, then compare with the recognition diagrams in the app. P1 share an algorithm with Ortega OLL Pi — if you know Ortega, start there.

FAQ
How many 2×2 CLL Pi cases are there?
6 cases (P1, P2, P3, P4, P5, P6) out of 42 2×2 CLL cases. Use the table below or open the app with ?group=Pi.
How do I recognize CLL Pi?
No yellow corners on top; one side has yellow headlights, the other 2 yellow stickers face away from each other.
Which Pi case should I learn first?
Start with P1 (same algorithm as Ortega OLL Pi), then learn the remaining 5 cases from the recognition diagrams.
