3rd Layer Algorithm in 3x3 cube

[GalPro]

Hi,
are there any algorithms that can solve all 4 corners of the 3x3 cube (3rd layer) once they are oriented correctly?

Thanks

Oh wow...

E-Perm anyone?

Plus X-perm(H perm + U2)

Look for those that move ("permute") just the corners but not edges.

If he's just solving corners then why would he need the X-perm?

X-perm(H perm + U2)

Um, did you try it? it does indeed permute all the corners while leaving the edges solved.

Do an H perm on a 2x2; tell me what happens.

That's why you have to add in a U2. X isn't really a permutation but with the U2, it switches diagonal corners.

Keep it on topic. We are trying to help beginners here, not have pointless discussions.

rjohnson_8ball's answer was good, anything after that was unnecessary.

Why do the H perm in the first place?

So when you do the U2 afterwards, the corners will be swapped.

what?

Because she asked if there were any algorithms that permuted all the correctly oriented corners, and thats one of them. I thought it was somewhat of a joke, because its probably not what she's really looking for, but it does answer the question.

 

[jtjogobonito]

So when you do the U2 afterwards, the corners will be swapped.

But if you are solving only corners then you do U2.

Duh. Any other obvious facts you would like to state?

Yes, you did not read her post correctly.

 

[rjohnson_8ball]

@jtjogobonito, I was going to mention also recommend the U2 + H-perm for the original poster too. Sometimes a beginner does not notice that swapping diagonally opposite corners is like swapping opposite edges, so the poster would want to know H-perm too.

Yes, but the poster said nothing about edges, so it is safe to assume that she is doing corners before edges.

Assuming the edges are permuted(and I think this is a reasonable possibility), you need to learn 4 algs.

The two A-perms
E
"chi"(H rotated 180 degrees. I refer to rotated standard perms with Greek letters.)

However, if you only want to permute edges relative to each other, (i.e. ignoring the edges), you only need two: One that switches adjacent corners or the equivalent of that(J, A, etc...) and one that switches diagonal corners or equivalent(Y, E, etc...).(The 2 A-perms are the same but for the edges, and H can't permute corners "relatively"(or edges for that matter.))

I think the thread has lost its focus abit, anyway,

In the last layer the edges are oriented correctly, and the corners are in a good place but twisted.

in the OLL link I saw these algorithms:

l2 U' R D2 R' U R D2 R
R2 D' R U2 R' D R U2 R
R' U2 R F U' R' U' R U F'
y2 R' F2 R U2 R U2 R' F2 R U2 R'
y2 R2 D R' U2 R D' R' U2 R'

I did one of them and I stayed in the same place

Thanks

EDIT: So apparently this is a question, but I don't see any question in there?
