What's the algorithm for this Permutation?

[brunson]

This method is from a 1981 cube book.

I'll describe it again, in a little more detail. HTML is not a good way for doing this. This is why I use Gabbasoft to test algs first before using them on a real cube.

Locate corner cubie to be rotated clockwise into the solved state into the upper front right corner. Don't rotate the top layer, rotate the whole cube.
Then do R' D R F D F' . The cube will be in a utter mess now. Rotate the top layer and not the whole cube so the corner cubie to be roatated anti-clockwise to te solved state is on the upper front corner and do F D' F' R' D' R. Then re-orientate the top layer again.

Hope this helps. I'm too poor to make Youtube videos.

Aren't you describing how to fix orientation of two adjacent corners? I.e. OLL 24?

HAHAHAHA

By definition I must be. I only know 2-look a the moment.

That's an E perm. I know it because I also had that. Just line up the edges and solve.

 

[esquimalt1]

That is a Y perm so don't even think about saying it's not. anyway if you want to be able to solve that using 2 look PLL, one of your options is putting the 2 corners that need to switch on the Top Left and Bottom Right then do this algorithm: F R U' R' U' R U R' F' R U R' U' R' F R F'

Did you look at the previous posts? There is absolutely no way that that can be an E perm... 2 adjacent edges need to be switched.

It is an E-Perm under 2-Look PLL. It is a Y-Perm under 1-Look PLL.

2 edges cannot be switched unless you switch 2 edges or 2 corners too

 

[*LukeMayn*]

2 edges cannot be switched unless you switch 2 edges or 2 corners too

so is it impossible to move 3 edges

 

[Rikane]

Technically, a 3-cycle is two edge or corner swaps.
I don't remember where I read that but it was somewhere.

To the OP:

NOTE: I do NOT want to know the FULL PLL algorithm for this case. I'm still only using 2-look PLL. I just want to be able to orient the corner pieces diagonally in ONE nice short algorithm. I will permutate the edge pieces in their own algorithm in the next step.

I'm sure you already know that you can fix this PLL using two A-perms.

If you want to do it in a single algorithm you can go to one of the many, many PLL guides on the web (http://www.speedsolving.com/wiki/index.php/PLL) and chose any PLL case that only moves two opposite corners (Y, N or V). Pick one, any one.

FWIW, you won't be using a 2-look PLL until you know how to do corner's in one alg, then edges in one alg. Learning Y, N or V will accomplish corners since you already know cw and ccw A perms, you'll then need both U's, Z and H. http://cubefreak.net/speed/fourlook.html
