4x4x4 Edge Problem (2 last edges)

[Phisherman]

Hi guys ! I have a problem. :confused:
All time i try to solute the 4x4x4 Cube i got a edge problem.
The 2 last edges are interchanged.
How can i swap them ?

Here is a picture you can see the problem:

The colors are (oriented to the picture):

top - yellow
right - red
front - blue
left - purple
back - green
down - white

I hope you can help me !

do a T perm with those corners both on the right. then do the pll parity with the incorrectly positioned edges in the front and back layers

Purple side? What is this, a virtual Eastsheen?

Do r2 R2 U2 r2 R2 u2 r2 R2 u2 U2 and then you have a T or F perm.

 

[Phisherman]

T perm F perm ???
Can you please write it all?
i dont know waht you mean with T or F perm...srry !
And yes, its a virtual Eastsheen^^

 

[Tetris Cube]

If you don't know them, just do regular 2 look PLL. I assume you know how to do that, otherwise I have no idea why you did OLL...

 

[Phisherman]

I did this tutorial and solve it then like a 3x3x3.

t perm is R U R' U' R' F R2 U' R' U' R U R' F'. yeah.

 

[Tetris Cube]

You should be able to solve it now, if you haven't already. After the parity fix, the 4x4 is now in a legal 3x3 position.

 

[Phisherman]

Ok, i hold the cube like the picture and then i do

(Rr)2 U2 (Rr)2 u2 (Rr)2 (Uu)2 and R U R' U' R' F R2 U' R' U' R U R' F' ?

 

[Tetris Cube]

You would have to do a y' before the T perm. (Counterclockwise rotation on the Y-axis, the unsolved corners will be on the right)

 

[Phisherman]

can you write the y' perm ?

 

[Tetris Cube]

It's not a permutation... lol.

It's a rotation. As in, you literally, rotate the cube. After the rotation is complete, blue will be on the right.

 

[Phisherman]

Damn, i dont understand it...srry.

 

[jcuber]

Just go to www.bigcubes.com

look at the parity errors for the revenge, use those algs, and finish solving it like a 3x3.

u2r2U2(r2R2')U2r2u2
y'
RUR'U'R'FR2U'R'U'RUR'F'

 

[Phisherman]

When i do u2r2U2(r2R2')U2r2u2 i hold the cube like in the posted picture from the first thread. After the algorithm it is more mixed than before. When i after this do the Y' rotation, so that the blue side is on the right and then do the RUR'U'R'FR2U'R'U'RUR'F' it doesn't work. What do i wrong?

 

[Tetris Cube]

If it looks scrambled after the first algorithm, then you did it wrong. Only the top layer should be incorrect, but it should be completely oriented like it was before. Watch Lucas's java applet, it shows exactly what to do, and even highlights the moves while it's doing them.
