Additional VHF2L cases

[Kenneth]

I just found there is a third state where the pair is connected from where you can do VHF2L.

Edge is in the slot but unoriented, corner at Urf makes a connected pair. Because the edge in the slot is unoriented there are only odd numbers of edges oriented in LL possible making it 1 or 3 oriented edges. The single oriented/unoriented edge can be at 4 places making it a total of only 8 cases and of those 4 are mirrors.

I post algs later, for the 1 edge cases I found a 6 turn and a 8 turn but the 3 edge cases are harder, I got 11 (STM!) so now I will use a tool to see if there are shorter ones.

Edit: how do you make CubeX ignore LL-edge permutation? (is it possible?)

More edit: OK, got the algs, 1R = 1 unoriented edge at the R-side, 3R = 3 unoriented, the one oriented at R-side, same for F, L and B. F is mirror of R and B is mirror of L.

1R
F' U F R U2 R'
F' U F U' R U' R'
R U' R B' R' B R' ... nice, do R U' l U' R' U l' =)

1F
R U' R F' U2 F ... my usual alg
R U' R' U F' U F
F' U F' L F L' F

1L
R U2 R' U F' U2 F
R U2 R' U2 F' U F
U' R' F R F' R U R'

1B
F' U2 F U' R U2 R'
F' U2 F U2 R U' R'
U F R' F' R F' U F

3R
F2 L F L2 U' L F
U2 R B U' B2 R B R2

3F
R2 B' R' B2 U B' R'
U2 F' L' U L2 F' L' F2

3L
R2 B' R' B2 U2 B' U' R'
F' U F2 R' F' R2 U2 R'
F' U L' B' U2 B L F

3B
R U' R2 F R F2 U2 F
R U' B L U2 L' B' R'
F2 L F L2 U2 L U F

Note that the ZB-cases are the same but with a leading turn

Yes it's possible there is a trick for it, you only will give the orientation of the pieces. Hold CTRL while clicking on the sticker that's oriented. It will show vague vertical yellow lines. This way it will only make sure the orientation of that piece is correct and not look at the permutation.

Thank's Erik

I don't think I understand your description. How does this differ from case 7?

 

[Kenneth]

case 7??

I have not got a clue

My pair is at FR-UFR having the corner D colour in the U-face. As far as I know that's not one of the usual VH cases.

Mabey you are refering to the normal F2L cases and are not familair with VH-F2L? The goal is to orient LL-edges while placing the pair.

Oh, I'm sorry, you're talking about VHF2L, I read ZBF2L.

Where do you get Xcube? Does it run under wine?

Thanks,
e.

Edit: Man, me reading skills are in the toilet today. CubeX, not Xcube... never mind.

 

[Kenneth]

I think cube explorer is windows only but I'm not sure.

Get it from here: http://kociemba.org/cube.htm

 

[brunson]

Yeah, I have it, it runs under wine, which is awesome since I don't have windows (and never will).

Edit: Oh, look. A new version. Time to upgrade, thanks for making me notice.
