2×2 CLL U algorithms
The U group has 6 of the 42 2×2 CLL cases: U1, U2, U3, U4, U5, U6. See all 2×2 CLL · other groups: Sune (6) · Antisune (6) · T (6) · L (6) · Pi (6) · H (4).
Recognizing 2×2 CLL U
2 adjacent yellow corners on top; the other 2 corners' yellow stickers face the same side (headlights).
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. U6 share an algorithm with Ortega OLL U — if you know Ortega, start there.

FAQ
How many 2×2 CLL U cases are there?
6 cases (U1, U2, U3, U4, U5, U6) out of 42 2×2 CLL cases. Use the table below or open the app with ?group=U.
How do I recognize CLL U?
2 adjacent yellow corners on top; the other 2 corners' yellow stickers face the same side (headlights).
Which U case should I learn first?
Start with U6 (same algorithm as Ortega OLL U), then learn the remaining 5 cases from the recognition diagrams.
