4x4x4 parity

[yoursturly]

i cant figure out how to do the oll parity and dont know how to prevent it,i keep on going to site after site and they keep telling me this parity

r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2

but this jus screws up my cube

please help,thanks

That algorithm works. You are obviously doing it wrong.


Also, Please do not post the same thread in multiple spot... That's just rude.

r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2

Works fine here.
The l r' r r2 are not two layer turns
just the slice only.

I actually fixes double parity but people still use it for OLL since there's already a 50% chance of there being a PLL parity and that alg's quick

AND USE THE 2 LAYERS

It will make it a lot more quick

I got a couple of diffrent algs, one for only OLL and one for both paritys.

I get e-mails about this alg all the time, and most times people are using B for Bottom, when it actually stands for Back.

I don't know if this is what is happening in your case, but it's what I see most of the time when people say the alg does not work when they view it on my site.

It doesn't matter if you used 2 layer turns or just the slice..
If you do 2 layer turns you flip the corners as well..

Sometimes I do slice turns when I can see that it will end up in an easier OLL =) and I'm sure many do that too...

Do we have an algo for swapping jus two dedges without disturbing centers? To be more precise do we have an algo for swapping only lUB and lDF dedges? I need it for r2 BLD.

Also is there an algo for rotating a center(180degrees) instead of doing 2 T/Y/J Perms

Also, you mean wings, not dedges (adjacent pairs of wings). PLL parity does that.

Why isn't that an algo?
Anyhow, I recommend (R U' R' U')5 if you want to look cool like Michael Gottlieb.

The wide turn one is way faster at least for me. Its like 4-5 seconds vs 8 seconds, and the OLL doesnt make enough difference to warrant slicing. I only slice if it is an OLL skip with just one edge flipped.

It's kinda funny how people assume that B is always for bottom. If B is bottom, then R is for rear? Then instead of right, we use the starboard face. Also, we could use the port face instead of the left face. The up face could be replaced with the T for top face. The front face would stay as F, you can't really use F for any other side of the cube. Instead of LRFBUD notation, we have PSFRTB notation.

You don't have to use the inner slice in that case.
If you usually use r2 B2 r' U2 r' U2 x' U2 r' U2 r U2 r' U2 r2 U2, you can modify that to R' (r2 B2 r' U2 r' U2 x' U2 r' U2 r U2 r' U2 r2 U2) x U2 R, using double layer moves as you always do. This way you can deal with a lot of case where only 2 corners are wrongly oriented, doing a setup move, OLL parity, U2, setup reverse.
