Parity is always r(a) perm?

[icetea666]

So,if i don't apply R perm to fix parity on 3x3x3,after solving the edges,am i ALWAYS left with R(a) perm after i solved corners?

Parity in this case means that you need to swap 2 corners and 2 edges. That can be done with both R-perms, J-perms or T-perm

If you don't tell which method you use we cannot help you

Ah sorry.I use old pochmann.So any of these three can occur at the end?

I also only know old pochmann. I start with the edges and when I have done an odd number of swaps that means I will have parity. I always make a Y' move and do the R-perm. Then Y again and continue with the corners.

I think it depends on what buffer pieces you use to get certain perms like the R J or T. But I haven't figured that out completely yet. But if you, just like me, use the "badmephisto" version of old pochmann then you will always end up with the same R-perm.

I use the L perm for parity

 

[StachuK1992]

I use the Jperm, but I'm weird.

if PLL cannot be set up < like 5 moves
then solving corners then edges or edges then corners is also a good way to fix parity

There aire also nice parity algs which are not PLLs.
For example: L' U L' Fw2 L U' L' Fw2 L2 U' (swaps UFL and UFR corners and UF and DF edges).

How would you solve "corners, then edges" or "edges then corners" when you have parity? The whole idea behind parity is that you cannot do that.

How would you solve a situation where ULF, ULB, DF and DB need to be swapped?

No, you should do the R perm *before* solving corners. What it does is it exchanges the edge-solving-side-effect (URF<->UBR) for the corner-solving-side-effect (UL<->UB).

Can anyone confirm this?

I think he means something like F-perm + M2 U2 M2 U2 for that situation.

 

[TMOY]

Why not simply F-perm with Rw2 as a setup ?

 

[yoruichi]

k looks thats justa really nub case lets say u have UFR UBR and UL FR
id do T- perm F' MUM'U2MUM' F
many times its better to do something like that than akward 3 or 4 move setup
like y R' E R since theres no rotations

 

[trying-to-speedcube...]

What about R U' R2 F-perm R2 U R' ?

 

[yoruichi]

what are u switching?
