[Help Thread] 4x4 Discussion

[Escher]

are you talking about individual dedge pieces, or edges in 'dedge form'? if either, you cannot swap two without messing up the rest of the cube in some way. if you would like to simply twist a single edge in dedge form with an algorithm, go on bigcubes.com. if you do not know how to do the last two dedges, follow the link to cubestation.

thanks, it is actually edges in 'dedge form'

 

[somerandomkidmike]

well I did what you told me to with my rubik's 4x4, and it turns amazing. I don't see why people would hate rubik's so much (although my old one had so many imperfections it wasn't funny).

Also I've tried doing FMC for 4x4, and I have got less than a hundred turns on occasion (which is the same, or less than i use for reduction).

...and I'm looking foreward to seeing your big cubes tutorial. (By the way, I've had a few sub-1:30 solves for 4x4, and getting better.)

 

[rachmaninovian]

you already have my tutorial
anyway, do you know all the CLL algs?

anyway TMOY you still don't have all the algs right? mm. if you would have to optimize all the damn algs for say 5x5....then...hehehehehe

 

[TMOY]

Depends on what you call having all the algs. I have already written out a set of algs for all cases, but it is still far from perfect. Here it is, hope this helps. Notations are Superset ENG.

[somerandomkidmike]

you already have my tutorial
anyway, do you know all the CLL algs?

anyway TMOY you still don't have all the algs right? mm. if you would have to optimize all the damn algs for say 5x5....then...hehehehehe

lol, for some reason I thought you said you made a tutorial i must have been seeing things.

 

[somerandomkidmike]

TMOY, thanks for the algorithms (If i don't see what the algorithm does, I'll just do the inverse)

and Rachmaninovian... I would post videos but i don't have a webcam right now

4x4x4 PARITY

I got a 4x4x4 Cube i know how to figure it out but i need help with the parity's, because i checked dan browns parity and it just mixed up my cube the way he did it so im wondering if anyone can please show me a site on parity for 4x4x4. The way i learned the 4x4x4 is to get all the centers and get pairs, to get ready to do 3x3x3 method. That's why i need parity algs becuase there's always a problem

If you can help me Thanks xD

 

[Samlambert]

OLL Parity: r U2 x r U2 r U2 r' U2 l U2 r' U2 r U2 r' U2 r'
Put the edge that need to be twisted at UF

 

[Vulosity]

The parity alg in his video is correct. You probably turned the wrong layer.

Is your problem PLL or OLL parity? PLL Parity is:

r2 U2 r2 U(u)2 r2 u2

 

[Jgig1991]

I use the algs from http://bigcubes.com/4x4x4/finalsolve.html

 

[Kirjava]

rU2rU2xU2rU2l'x'U2lU2r2 and l'U2l'U2xU2l'U2rx'U2r'U2l2 are my favourites.

 

[TsColin]

4x4x4... is it possible without parity?

Hey guys i've been working on solving my 4x4x4 and i'm at the last layer and of course i have parity. Is there any work around so that i can solve the cube and not get parity?

Thx,
Colin

 

[Vulosity]

I MIGHT and PROBABLY be wrong, but if you use the cage method, you won't get parity.

Parity's not much of a big deal. Two algs. That's it.

 

[jcuber]

No, it just happens. Luckily there are only 2 algs to learn, and the longer one just practice over and over until you have it memorized.

 

[ISuckAtCubing]

both parity are easy, the oll one almost dont even need to memorize

 

[TsColin]

Really? Could you tell me what they are because i'm watching Dan Brown >.> and i have these algs

1) 2U*, 2L*, 2U, 2l, 2U, 2L*, 2U*, R, U', L, 2U, R', U, R, L', U', L, 2U, R', U, L', U

2) 2R*, 2B, 2U, L*, 2U, R'*, 2U, R*, 2U, 2F, R*, 2F, L'*, 2B, 2R*

3) 2r, 2U, 2r, 2U*, 2r, 2u

4) 2U*, 2L*, 2U, 2l, 2U, 2L*, 2U* F', U', F, U, F, R', 2F, U, F, U, F', U', F, R

5) 2r, 2U, 2r, 2U*, 2r, 2u

and of course there all used for different situations

 

[Kian]

uhh, no. an oll parity fix is an awful alg, most people can't do it in under 5 seconds.

and no, there is no way to avoid it. just learn the two algs.

 

[Vulosity]

2) 2R*, 2B, 2U, L*, 2U, R'*, 2U, R*, 2U, 2F, R*, 2F, L'*, 2B, 2R* <-OLL Parity

3) 2r, 2U, 2r, 2U*, 2r, 2u

4) 2U*, 2L*, 2U, 2l, 2U, 2L*, 2U* F', U', F, U, F, R', 2F, U, F, U, F', U', F, R

5) 2r, 2U, 2r, 2U*, 2r, 2u <- PLL Parity

I really hate that notation.

 

[Deleted member 2864]

If you don't like parity, learn cage. THat's where I started. Eventually, you'll want to learn those two algs (only the oll one should give ya trouble). Redux is faster than cage.
