Nutella Pyraminx.

What is the best algorithm to solve only two edges of case nutella.

The particular case in which the centers are solved?

thanks

Shortest Square-1 parity alg? I still use the beginner's method so idc what it permutes, just as long as orientation is preserved.

E: nvm found that's easy to learn

Best alg I've found is:
(Rw' U' R' F R U2) (Rw2' F Rw U' Rw U' Rw)

This case is also a conjugated Jperm:
L F (R U R' F' R U R' U' R' F R2 U' R' U') F' L'

Thanks, it's been a while. Sorry to thanks so late!!!

I found some to (modulo starts positions) :

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

The one I use is the following :
y' R2 B2 R U' R2 y R U R U' R' F R2 y' R U R y because it's really finger-tricks friendly and the y regrip is not so awful in this case


Otherwhile, I have some nice algs in the same spirit...

F2 R' U' R D' R2 U R' U' R2 U D F2
F2 U2 L U L' U B2 D' R D F2 B2
R' D R F2 L D' L' D' L2 U' R2 U' R2 U2 L2 F2

I need an alg for this Ab-perm on this bandage cube. I use blue as the F face and yellow as the U face. http://imgur.com/a/uunF3

What're the best OLL and PLL parity algorithms that preserves center orientation (for Moyu 4x4 Fisher Cube)? I've checked the wiki, but I wanted recommendations

Edit: nevermind, found this: http://michael-gottlieb.blogspot.tw/2008/05/solving-4x4x4-and-5x5x5-supercubes.html

What is the shortest alg on a 2x2x3 that:

- swaps DFL and DBR,
- leaves everything else on the D side,
- can mix up anything on the U side,
- uses only <R2,F2,U>,
- If we do only the R2 and F2 moves in the algorithm (and leaves out the U moves), it does nothing.

Here is an example algorithm:
F2 R2 U2 R2 U2 F2 U' R2 U2 R2 U2 R2 U R2
(note that if we consider only the R2 and F2 moves: F2 R2 R2 F2 R2 R2 R2 R2 = nothing)

I need this for a parity alg on a crazy 2x2x3.

Is there a shorter algorithm with these properties?

If the case below occurs in the BL slot and I want to insert it into the BR slot, how do you guys go about doing that? Any rotationless algorithms or M-slice algs?

For rotationless, you could do U' L U L' U' L U L' U2 f R' f'

Not fast at all...but I guess this case never comes up for me since I use zz

Spoiler: Well, if the edge is at BL and needs to go to FR, and the corner is at UBL and needs to go to DFR, do...

U2 R2 u R2 u' R2

(that actually isn't what you are searching for... well, might be useful too :S)

All great algs! thanks for the help guys.

Any algs other than U2 R2 u R2 u' R2?

Any algs other than U2 R2 u R2 u' R2?

[obelisk477]

All great algs! thanks for the help guys.

I think (hope) you'll like

R' U2 R2 u R u' R'

even better. It's (sorta) 2 gen with (sorta) no rotations.

Can I get the alg that swaps just 2 edges as the last step of this video?

http://youtu.be/aYv_oB_PXSg

The case shown at the video appears to be this ELL:
Solved with: F' L' B L F B' U' B' U B

But if you are searching for the OLL that flips that two edges:

, you need the algorithm r U R' U' M U R U' R'

Or... if you are searching for an algorithm that just flips two adjacent edges, like this:

Then you will need r U R' U' r' U2 R U R U' R2 U2 R.
