In this page, I will show the algorithms I chose for the 4 cases of the Pattern 4.
I call this pattern “square”.
No. 45: UFR and UBR look at a side
https://www.speedcubedb.com/a/3×3/VLSUB/VLS_45
Algorithm: F’ (L’ U2 L U) F
Finger tricks: F’ by left thumb.

No. 47: UFR looks at a side
https://www.speedcubedb.com/a/3×3/VLSUB/VLS_47
Algorithm: R (B U’ B’) R’

No. 44: UBL looks at a side
https://www.speedcubedb.com/a/3×3/VLSUB/VLS_44
Algorithm: (R U’ R’) + OLL
My OLL is (f’ L’ U’ L U f).

No. 46: None of the CP looks at a side
https://www.speedcubedb.com/a/3×3/VLSUB/VLS_46
Algorithm: (F’ U F) (R U R’ U’) (R U’ R’)
The (F’ U F) sequence takes me time, but the following easy turns compensate it.
