PLL J perm

1. Ja perm:

x (R2 F R F’) (R U2) (r’ U r U2) x’ (a bar on L-face)

(R’ U L’) U2 (R U’ R’) U2 (R L) (a bar on F-face)

Finger tricks: R’ U L’ begging with regrip (thumb on U-face), and L’ by left “ring” finger maintaining the basic position, which makes the next moves stable and fast.

2. Jb perm:

(R U R’ / F’) (R U R’ U’) (/ R’ F R2 U’ R’) (a bar on L-face)

Finger tricks: It is possible to complete this algorithm without any regrip, but I prefer inserting regrips at 2 positions indicated by “/“ mark. I use R U R’ F’ (marked in blue) by Trigger (R U R’) + Michael Trigger (F’), sliding my thumb to D-face during the Trigger (smooth regrip), so that Michael Trigger is easily turned. The second regrip should be done during the preceding U’.

(L U’ R) U2′ (L’ U L) U2′ (L’ R’) (a bar on F-face)

Finger tricks: L U’ R (same as above explanation)

All these 4 algorithms are short and easy.
