The 21 PLL cases

Corners Only

Name	Diagram	Algorithm	Comments
Aa		x (R' U R') D2 (R U' R') D2 R2	This is a basic corner 3-cycle. It is one of my favorite and fastest algorithms. Perform the D2s with the left hand and everything else with the right.
Ab		x R2 D2 (R U R') D2 (R U' R) [y'] x (L U' L) D2 (L' U L) D2 L2	This is just the inverse of the other A perm. It is performed in a very similar manner.
E		x' (R U') (R' D) (R U R' D') (R U R' D) (R U') (R' D')	This alg is just two orientations performed consecutively.

Edges Only

Name	Diagram	Algorithm	Comments
Ua		(R U' R U) (R U) (R U') (R' U' R2) [y2] (R2 U' (R' U' R U) (R U) (R U' R)	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		(R2 U) (R U R' U') (R' U') (R' U R') [y2] (R' U R' U') (R' U') (R' U) (R U R2)	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		(M2' U) (M2' U2) (M2' U) M2'	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		(M2' U) (M2' U) (M' U2) (M2' U2) (M' U2)	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

Name	Diagram	Algorithm	Comments
Ja		(R' U L') U2 (R U' R') U2 (L R U')	I perform the R of the [R L] a split second after I start the L so that I can immediately perform the U' to AUF when the L face has been moved to where it belongs.
Jb		(R U R' F') (R U R' U') (R' F) (R2 U') (R' U')	This is the same as the T perm with the last four moves instead performed at the beginning.
T		(R U R' U') (R' F) (R2 U') (R' U' R U) (R' F')	This is the T permuation. It is long but definitely very fast and easy. It can be performed in almost one swift motion without any readjusting of the fingers. Note that it is a combination of two easy orientations.
Rb		(R' U2) (R U2) (R' F R U R' U') (R' F' R2 U')	This is a pretty straightforward alg that flows pretty nicely.
Ra		R U R' F' R U2 R' U2 R' F R U R U2 R' U'	You could also just mirror Rb, but this alg is more right hand friendly. Notice the similarity with the Jb permutation.
F		R' U' F' (R U R' U') (R' F) (R2 U') (R' U' R U) (R' U R)	This is a T permutation with a 3 move setup in the beginning and a cancellation of one of those moves at the end.

Cycling Three Corners & Three Edges

Name	Diagram	Algorithm	Comments
Ga		(R2' Uw) (R' U R' U' R Uw') R2' y' (R' U R)	This alg has a pretty decent flow to it and can be performed almost in one motion until the rotation.
Gb		(R' U' R) y (R2' Uw R' U) (R U' R Uw' R2')	This is the inverse of Ga. Note how similar they look. I perform this one almost exactly the same way.
Gc		(R2' Uw' R U') (R U R' Uw R2) (Fw R' Fw')	You could rotate and insert the pair instead of performing the last three moves as shown.
Gd		(R U R') y' (R2' Uw' R U') (R' U R' Uw R2)	This is just the inverse of Gc. I execute it very similarly because most of the moves overlap in the same manner.

PLL

Cycling Three Corners & Three Edges - Detecting Ga, Gb, Gc, Gd perm

- Put the good corner & edge at its position
- Turn the cube such that to have the "head lights" (the corners with same side color) on the L face
- Ga: good corner on F face
  Gb: good corner on R/back face
  Gc: good corner on B face
  Gd: good corner on R/front face

  Ga: (R2' Uw) (R' U R' U' R Uw') R2' y' (R' U R)      R2 R' R' R                      Uw U U' Uw'
  Gb: (R' U' R) y (R2' Uw R' U) (R U' R Uw' R2')       R2 R' R  R                      Uw U U' Uw'
