Name | Diagram | Algorithm | Comments |
---|---|---|---|
Ua |
|
This is just a simple 3-edge cycle. It is almost as fast as the corner cycles. I solve this case with the bar at the front or the back. | |
Ub |
|
This is the inverse of the other U perm. I place my hands slightly differently for this algorithm. I solve this case with the bar at the front or the back. | |
H |
|
This is extremely easy to recognize and can be performed VERY quickly. The M'2 is actually performed as (M'M') with rapid pushing at the back face of the M layer with the ring and then middle fingers. | |
Z |
|
The Z permutation is performed very similarly to the H perm. The last U2 is not necessary if you account for it before the algorithm. |
Swapping Two Adjacent Corners & Two Edges
Cycling Three Corners & Three Edges
To recognize these PLLs:
- Put the HEADLIGHT on the left
- Observe the position of the BLOCK: if it is as the FRONT (resp. FAR RIGHT, BACK and CLOSE RIGHT), then it is a Ga (resp. Gb, Gc and Gd) permutation.
To remember the algorithms, observe the sequence of RIGHT face versus sequence of UP face:
- Ga:
R2 R' R' R
vsUw U U' Uw'
- Gb:
R2 R' R R
vsUw U U' Uw'
- Gc:
R2' R R R'
vsUw' U' U Uw
- Gd:
R2' R R' R'
vsUw' U' U Uw
Permutations Of Two Diagonal Corners & Two Edges
The Na / Nb permutation variants come from Finger Trick - How to Execute the N Perms Like a Pro (cyotheking).
