Anyone know a quick 4x4 OLL parity with slicemoves? or just a fast OLL parity

 

[MaeLSTRoM]

I know one that doesn't preserve 3x3 stage, but its fast and only cycles 4 edges in the M-ring:
r U2 r' U2 r' D2 r D2 r' B2 r B2 r'

r U2 r' U2 r' D2 r D2 r' B2 r B2 r'

I know a much shorter alg that cycles 4 midges too .

But does it flip a single edge for OLL parity?

I used to use r U2 r U2 r' U2 r U2 l' U2 r U2 r' U2 M r' U2 r', where lowercase letters are slice moves. This alg is pure (it doesn't affect anything else).
Then I realized that slice moves were slowing me down, so I switched to r2 B2 U2 l U2 r' U2 r U2 F2 r F2 r' U2 r2, where lowercase letters are wide turns.

I can't understand why you would want slice moves over wide turns. :confused:

Try this alg (lowercase letters are wide turns)

r U2 x r U2 r U2 r' U2 l U2 r' U2 r U2 r' U2 r' x'

I need a new Ra perm (UBL and UBR swap + UL and UF swap), any suggestions?
Currently using: (y2 z) U R2 U' R2 U F' U' R' U R U F U2 R (z')
Damn slow.

Any one of these --

[L U2' L' U2'] [L F'] [L' U' L U] [L F] L2' U

y2 [R U2 R' U2] [R B'] [R' U' R U] [R B] R2 U

r U2 x r U2 r U2 r' U2 l U2 r' U2 r U2 r' U2 r' x'

That is very nice, thank you

If you're ok with the starting postion being a U turn away from that (which should be fine cause it's still a good position for recognising the case) I switched to this one the other day that I got from Breandan (demonstrated here(7:02), and also in his sub-1 video here)
R U' R' U' R U R D R' U' R D' R' U2 R' (U')
It's regrip less, and the D' can be done as a left hand push or with your right hand, whichever is more comfortable.

For the last 3 algs for Pi, could anyone give me the COLLs you use? I have trouble sub2ing the last one, and the others are barely sub2. The last one is just awkward moves which makes it hard to sub2, I'm positive it's fast but I just suck.

Eido U2' for the last U2

 

[Jakube]

I need a good alg for orienting ULB and DFR for Bld (so nothing else should permutate)

 

[MaeLSTRoM]

[r2 y, R' U2 R U R' U R U2 R U2 R' U' R U' R'] That's for the U sticker facing B
[r2 y, R2 D R2 U' R B2 U' B2 U R2 D' R] That's for the U sticker facing L

I've recently become interested in OH. I'm competing tomorrow and I'd like the fastest diag corners OH PLL alg you know. (I'm going to 2-look Na, Nb, and V.)

2) Z-Perm + Opposite PLL parity

Finally, here's an algorithm I made for this case.

It may not be so pretty (I think it is, but I'm me), but it is PURE, i.e., it doesn't rotate any centers. It's 19 btm.

l r (Dw u') L R u' L' R' (Dw' u)
M2
(Dw' u) L' R' u' L R (Dw u') l r

EDIT:
If you invert the two u' s, then you can cycle the 4 dedges in the clockwise direction. (Hence, which ever direction the two u moves go is the direction the 4 dedges go.

In addition, if you invert the last two (Dw' u) turns, we have a pure alg for the other "oriented" 2 4-cycle cases. This of course would only be used in K4.

l r (Dw u') L R u' L' R' (Dw' u)
M2
(Dw u') L' R' u' L R (Dw' u) l r

instead of
(U') R' U2 R U R' U R2 U' L' U R' U' L
I use
R' U2 R U R' U R U2 L' U R U' M'

This is even one of my favorites
R U' L' U R' U L U L' U L
But maybe You like it more if you first do U2 and than mirror all the Ls to Rs (not sure this sugestion was already made )

New Request:
OLL parity + any EPLL alg (so that it does one, can be centre-unsafe and better if it only affects EPLL)

 

[nccube]

An MU alg for UB-BD-FU (Optimal, if possible)

 

[lucarubik]

and an RU for UB FR BR

 

[Christopher Mowla]

New Request:
OLL parity + any EPLL alg (so that it does one, can be centre-unsafe and better if it only affects EPLL)

Do you mean something like this?
M U r' U2 r U2 r U2 r2 F2 r' U2 r' U2 F2 r2 U M' (18)
