help in solving 4×4×4 parities intuitively

[mailong]

hi,

I have been trying for a while now to solve the single oll parity(I think that's what they call it, I am not that good with name XD),and the two corners swapped parity(I read this one can be done by commutators, I know commutators bt I haven't been able to figure it out)

I'd really really really.... appreciate it if someone can give me the solutions if possible without things to memorize... XD

Learn the Concept of a commutator but you just need the PLL parity where one edge will be flipped

Orientation parity can simply be solved by r. That way, you can convert the 2-cycle, which is parity, into a 5-cycle, which isn't parity. Then you can use commutators to fix the centers without messing up the edges. I recommend you learn an orientation parity algorithm.

As for the permutation parity, the easiest way to solve it is using Uw2 Rw2 U2 as a setup to put 4 edges into the r slice, then doing r2 you do the 2 2-cycles, preserving centers because you set it up like that, and then you undo the setup U2 Rw2 Uw2. This is an algorithm some people use, other algorithms are Rw2 Fw2 U2 r2 U2 Fw2 Rw2 and r2 U2 r2 Uw2 r2 u2.

What?

yeah. there are really easily simple commutators for solving any big cube. But it takes more time, Note : i have done the commutator for 4x4x4. But it can be applied to any big cube.(Provided you understand it)

guys srry I still don't get it,I am not that's used to these stuff cause I did all the cubes without even using any algorithms,the only reason I understood commutators was because I could go back and forth through the steps in Ryan Heise site till I got the concept.
@trying-to-speedcube...: this may be
a very stupid question bt is Rw the same as Rr?.
@zosomaniac:I can avoid the the edge swap parity but I still get the edge flip parity sometimes with the two corners swapped parity,I followed your video-even though it took a lot of pausing- I could get nearly most of it,even though I don't do it exactly the same way,I still end up with the parity solved even if part of the cube gets scrambled,but I can't get why it was solved and why I switch the edges that way and then solve them. I followed many videos and algorithms-at least the algorithms I could understand- bt I can't understand it yet,I don't want to memorize something then try to figure out how it works after memorizing it for ages-that's apart from the fact that I am bad at memorizing-these two parities are the only things keeping me away from solving any cube T.T
