4x4 OLL Parity Algorithm [video]

[deadalnix]

r' U2 l (x) U2 l' U2 r2 (x') U2 r U2 r' U2 (x) U2 r2 U2

can be done :

r' U2 r U2 r' F2 r2 U2 r U2 r' U2 (x) U2 r2 U2

One F2 and you avoid 2 regrips and l moves.

ah..forgot to specify i do it pure. so small letter turns are only slice turns...not double..

 

[Robert-Y]

What? How on earth can you do the pure alg so fast? Can you make a video please?

 

[rachmaninovian]

would sub 4.5s do? I'm too lazy to aim for anything lower...xD

is sub 4.5 enough (the video)?

or sub 4?

please say the latter

 

[Robert-Y]

Anything under 5 secs would do for me.

Sub 4.5 would be amazing, my OLL parity is at least 9 seconds...

really? i started using lucas's alg and i'm around 5.8-6 .. that's with delays.. i memorized it literally 5 mins ago.

what does the "x" in algorithms mean?

lol bump

x is a cube rotation, like the entire cube is doing R

haha thanks. im kinda new to this speedsolving thing

Unfortunately it doesn't seem to work using double turns. At least not the way I'm doing it.

I'm still a big fan of Lucas's parity alg:
r U2 x r U2 r U2 r' U2 l U2 r' U2 r U2 r' U2 r'
(To do it on an odd cube, include the middle layer in the second r' turn.)

when doing lucas's parity algorithm are the "r's" both the inner right layer and the right side, or just the inner layer?

You did bump a thread nearly 2 years old. Were you aware of that? anyway, to answer your question:
You have to include the inner layer, but the outer layer is optional. I typically execute the r as Rr (outer and inner) because it can be executed faster. However, you may not want to flip the outer slice corners, in which case you would only use inner layer turns.

So if you only use r as an inner layer turn, it would be:
r U2 x r U2 r U2 r' U2 l U2 r' U2 r U2 r' U2 r' U2 L R'

Mess around with it using inner and inner+outer and look at the effects.

algorithms 4x4x4 parity?

Hey guys i want algorithms of 4x4x4 parity Oll and Pll.Can write those algorithms thanks.And how many algorithms are for parity?

Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw'

Uw2 r2 U2 r2 U2 r2 Uw2

 

[MaeLSTRoM]

PLL Parity: r2 U2 r2 Uw2 r2 u2 Or Rw2 B2 U2 r2 U2 B2 Rw2
OLL Parity: Rw U2 Rw F2 Rw F2 Rw' F2 Lw F2 Rw' F2 Rw F2 Lw' U2 Rw'
Double Parity (OLL and PLL): Rw2 B2 Rw' U2 Rw' U2 B2 Rw' B2 Rw B2 Rw' B2 Rw2 B2

Here is a thread with lots of OLL parity algs: http://www.speedsolving.com/forum/showthread.php?6026-4x4-OLL-Parity-Algorithm

My fav is: r U2' r U2' r' U2 r U2' l' U2 r U2' r' U2 x' r' U2 r'
The 'r's and 'l's could be inner slice turns for pure parity, or wide turns if you don't mind messing up the corner orientation (oh, but the x' should also be a M if you're doing slice turns).

for PLL parity I do slice turns: r2 U2 r2 Uw2 r2 Uw2 U2 (if you're switching the front and back edges. if you have the front and right edges needing swapped I do R U R' U ( r2 U2 r2 Uw2 r2 Uw2) U' R U' R'
