Trouble with A-Perm

[milkolate]

I can identify which A-perm should I use, the clockwise or the counterclockwise.. Is there an easy way for detection?

I look at the left side, if the edge piece is the opposite to the face it's anti-clockwise, if the edge piece isn't (then it would be to go onto the front/back depending what way you hold your cube to do the clockwise algorithm) then it's clockwise.

isn't the A-perm the corner 3-cycle? O.o

the way I do it is to put the 2 corners that have the same color in the front...then I just look if they'll cycle to the left or to the righ

I was referring to the corner PLL (a-perm) not the edge PLL (U-perm)

The front or the back?

Put the 2x2x1 on the F face
Then you'll have 1 of these 2 cases:

1. See if the corner that needs to be switched shares a color with the edge piece it's next to.(the edge piece on R or L face, depending on which algorithm you use)

2. The corner is opposite colors of the 2 edges it's next to.

which case is counter, which case is clockwise?

additional question: I use the R' F R' B2 R F' R' B2 R2 regardless of which A-perm is needed. I find it to be faster, any comments?

 

[milkolate]

I got it. A-perm should only be used if the adjacent edges are properly placed.

A perms are easy for me, i kinda modified mine a little, but its fast as hell!
its goes:

(R' F l)(D2 R U' R')(D2 U2)
For the D2s, i use my wrist.

(for the counter clockwise just do the opposite.)
