This is a place to talk about what you think causes parity on different cubes. There is 4x4, 5x5, 6x6, Void cube and many others.:confused:
What causes Actual parities, is a 2-cycle of some type of pieces, an example is OLL parity, which is a 2cycle of wing edges.
There are also vitrual parities, which are cases that are called parity, but are not, such as PLL parity, which is a 2+2 cycle, but if the case was on a 3x3, it would be a parity.
As for solving them, Once you know the algs, its easy
You can't cycle 2 pieces (unless it's a 2x2) on a nxnxn cube. On a 4x4 it isn't about cycling 2 pieces, it's about placing the center pieces in the wrong order.

U2 L U2 R' U2 R U2 F2 R F2 L' B2 R2) Flips one edge (two pieces) and Rotates the top center by 180 degrees. Obviously you don't notice this when the center is all the same color, but Do a Bw move and then do the algortihm, you'll notice it.
Your first sentence is not completely correct. You are missing a non-trivial special case where you can perform a pure 2-cycle on an nxnxn cube. I won't tell you which n, though. I'll let you figure it out
I only have a 4x4 and void, but the permutation parity on the void is hard for me because the alg I know fixes the permutation, but messes up the orientation.

Awesome, thanks so much, without you we wouldn't be able to talk about it! You're so generous.

You're welcome!:tu:tu
What about square-1? The algorithm is hard to remember, and it's tricky to do fast without making a mistake and having to start over again.
I believe Stefan was being sarcastic there.
I share in this belief.
