Faster big cube algs?

[Joker]

Hey guys. I was thinking earlier today about the algs to solve parity on big cubes. These algs use slice moves, and can do things that are impossible on a 3x3, such at flipping a single edge.

I was wondering if this could be used to make OLL and PLL cases better. The advantage is you can use slice moves that are not available on the 3x3.
This might have been though up before, but I thought it'd be worth a try.

What do you think?

R U R'

Wat?
You mean making an adjacent edge swap into a opposite edge swap?
I meant when you are in the 3x3 LL stage, WITHOUT PARITY, solving the OLL/PLL with fewer moves/with a faster alg by using slice moves, which you would not be able to do on a 3x3.

but slice moves take longer and are less finger-trickable.

I think it's possible, but these algs would be very hard to find. And slice moves are not so fast as normal OLL/PLL imo.

Just made it up. Kinda weird XD

Not if you are good at them...

I intended this to make slow PLLs faster, like making N perms not suck.

 

[vcuber13]

and you think making an alg full of slices will be faster for an n perm?
and what about 5x5 and 7x7?

I'll try this...4x4 I'm guessing? And are the small letters slice moves or double layer turns?

Yes.
Inteded for even layered cubes.

you wanted an N perm...

I DISAGREE

LOL Thom. Awesome 20+ move algs!

EWWWWWWWWWWWW

Fw2M2Fw2UFw2M2Fw2U

Equivalent to the 3x3 alg F2M2F2 U F2M2F2. (What, you didn't know that alg? )

Rw2U'lD2l'UlD2l' x2 U2lU'L2Ul'U'L2U'Lw2

Neat, but it's a lot longer than RB[PLLpar]B'R'.

Ha, wow. That is a pretty long alg. Here's another for this case: Rw2 D l U' R2 U l2 U' L2 U l U' M2 U' D Lw2


@ this topic: I don't think anything slice-based is going to end up faster than the standard 3x3 algs, especially for a fast turner who can do outer slice algs quickly.

 

[Joker]

Lol with Kirjava spitting algs, I don't think it'll be that hard to find

 

[Kirjava]

EWWWWWWWWWWWW

My favourite part is "rblr"

Equivalent to the 3x3 alg F2M2F2 U F2M2F2. (What, you didn't know that alg? )

Well, I derived it from a 4x4x4 alg. Point is, you can use double layer turns in some 3x3x3 algs if you wish.

I agree. Still gonna keep trying though

From the wiki:
A 4x4x4 special: Note: Rra = (R + r) + (L + l) :: (y) Rr U2 Rra' U2 Rr U2 Rr' U2 Rra U2 Rr'

Rw U2 Rw' F R' F' R Rw U2 Rw' [U'] is a Y-perm, b-i-t-c-h-e-s!
Or done as Rw U2 Lw' U R' U' R Lw U2 Rw' [U']
Or their inverses.

What I tried was flipping UF with RwU2Rw', replacing UF with another edge, and undo RwU2Rw'. Simplest are (Rw U2 Rw') (U' R U R') (Rw U2 Rw') and its inverse (Rw U2 Rw') (R U' R' U) (Rw U2 Rw'), but those particular ones are better done with the seven moves regular OLLs.
