# Can anyone explain me the logic behind a J perm(or similar)?

I learned to solve a Rubik's cube recently by intuition and some basic cube theory (not by myself). At the last step, I use corner 3-cycles and corner rotations to reach the final solved state. I understood corner rotation this way: If a corner is rotated CW, then another corner can be rotated CCW without disturbing any other part of cube. Similarly I understood a corner 3-cycle this way (using commutator notations):

• A - replace a corner C1 from left face from right face C2. [U'RU]
• B - Rotate left face so that a new corner from left face C3 gets the place where C1 was. [L]
• A' - place the corner C3 from where C2 was taken. [U'R'U]
• B' - Rotate left face the other way. [L']

Move: ABA'B'
Result: A corner 3-cycle.

I can't apply the same logic to do a 2 corner swap + 2 edge swap.

Can any one explain how J perm (or any other PLL which swaps 2 corners and 2 edges simultaneously) works?

P.S : I learned to solve the cube from this video.
