Well, I guess it's time to start putting in the effort to learn the intermediate version of Sarah's method!

(A bit off-topic, but is there a better Z-Perm and H-Perm on skewb?)

H-perm: (R L R L' R' L') (F' R F R')
in FCN, it's (R L R L' R' L') (U' L U R')

My skewb locks up quite a lot sometimes. Is there a way to fix it or should I just turn more accurately?

It's occurred to me that there are a multitude of notation systems for skewb, and with a skewb milestone right around the corner, I think that a lack of a standardized notation system will make generating and sharing algorithms a nightmare.

Because of this, I'd like to propose a notation system that maintains WCA FCN while labelling the other four corners based on other existing notation systems:

Standard Skewb Notation Proposal

The puzzle is held with three faces fully visible, where the U face is on top, the F face is on the front-left, and the R face is on the front-right.
The D face is opposite the U face, the L face is opposite the R face, and the B face is opposite the F face.

The corner piece adjacent to the square-shaped centre pieces of any three adjacent faces A, B, and C, will be said to be in the ABC position.
Thus:

U is a clockwise twist of the layer around the UBL corner.
R is a clockwise twist of the layer around the DBR corner.
L is a clockwise twist of the layer around the DFL corner.
B is a clockwise twist of the layer around the DBL corner.
The four twists listed above comprise the official WCA scrambling notation for Skewb, also known as "WCA FCN".

F is a clockwise twist of the layer around the DFR corner.
r is a clockwise twist of the layer around the UBR corner.
l is a clockwise twist of the layer around the UFL corner.
f is a clockwise twist of the layer around the UFR corner.

' inverts a move.

How does this sound?

Force one of the other centers to be solved instead. Can force at least one centre solved with 2 sledge/hedge every time. I never use the cat3 cases.

It works nice, if we got opposite centers on R/L or U center is on F/U/B face. But sometimes nothing matches (it propably requires sledge/hedge at least 2 times) and I have no idea how to solve that. It would be great if somebody could post these three 1-look algs.

Could you elaborate.. Im having a hard time recognizing/performing the cat3 cases..
How you determinate if either do hedge or sledge to place on top the forced center? or am I just totally misunderstanding this?

Sledge and hedge do the same thing to the centres. F and B swap, U and R swap.

If you take this understanding of how sledge and hedge work to a deeper level, you could force a centre adjacent to your layer to solve instead of attempting to solve the U centre.

Then what you're left with is just a L4C+CLL case from my method =)

And as for corners, both are a Pi orient/no swap right?

Yep!

Property of skewb: Once the corners of one layer are permuted, so too are the corners of the opposite layer. The alignment of the two tetrads of corners with respect to each other can be done in at most two twists.

Does anyone else use Ranzha's method?
I do! I do!

I'm trying to finish documenting the method before I put it online. It could take a lot of time mainly because I have to translate all the algs I generate from URLD to FRLB

Could somebody post an alg for that case CLL+U center

Two questions (this should be about hardware but this is skewb discussion)

1. How can I get off the corner caps for the Lanlan skewb (on the rotating axes)? Those things are impossible to get off with a razor blade.
2. Good Z-Perm?

What are the equivalents on Skewb of sub20/15/10 on 3x3?

#### TiLiMayor

##### Member
I think sub 15/10/5 could be a close parallel to your listed ones..
Eventually times will get closer to pyraminx ones and could be used as a reference..

I've stopped trying to remove them. It's probably more worth your while to get a new skewb if your fixed centres bend.
