How do you pair up your edges?
 1 at a time 33% [ 8 ] 2 at a time 29% [ 7 ] 6 at a time then the rest 2 at a time 17% [ 4 ] 6 at a time then 4 and then 2 4% [ 1 ] a mix of the above 0% [ 0 ] you don't pair up your edges cause you use a different method 17% [ 4 ]

So, how do you guys solve your edges on the 4x4 cube? You do one at a time, or 2? Or first 6 and then 2? Personaly I do 2 2 2 2 2, or when I see nice things I do 6 2 2 2.

I used to do 6-4-2, but now I use cage, so I chose the last option.

No pairing, k4. Piece by piece insertion.

Used to use two at a time, though.

I do one at a time...

I'm going to learn to do more though. I'm really just now getting into speedsolving with the 4x4 instead of just plain solving.

I do two at a time, but I think I lose a second or two because I like to keep the first two edge-pairs in the back two slots (so all available edge-wings are on U or D) which means I need to do a y2 after the first set of edge-pairs. Is there a better way?

I was trying to do 6-2-2-2 at one point.
Then I asked Chris Hardwick (at the Nationals) whether he paired 6 (I might have asked him about the 5x5x5, but I'm pretty sure it was the 4x4x4), and he told me that he doesn't normally do that because of chain issues. Apparently, not worrying about that is worth the little extra moves.
So, since then, I always do 2-2-2-2-2-2 (with commutator exceptions at the end).

How does one do 6 edges at a time? I'm assuming it's getting them all set up and then doing an algorithm? I would think just getting them properly positioned could take longer than just doing 3 of the 2 edge set ups. Of course, I'm not a speedcuber, so I'd be slow no matter what.

It might be good just to know how to do a large amount at one time. I know once when solving, I ended up making one split and it solved 4 edges at a time, but I didn't know how to keep them while restoring the centers, so I had to do them one at a time.

I might make a small tutorial on edge pair up then on my site, but I need to know who is interested in that first...

there is a method for 2 and 6 edge pairing, complete with videos and explanation on bigcubes.com. i use 6-4-(2) because a lot of times it does work out, and if i do my 4 right i skip the last 2. chris h uses 2 at a time solving, while frank uses a similar approach to me with 6/4/2 kinda stuff. there are drawbacks and advantages to both ideas, so its really really worth to find out what works best for you. i struggled with 2 at a time for about a month, then when i switched to 6 at once, it was immediately easier and faster than 2 a at a time.

the big disadvantage of 6 at once is when the cycle fails, but there are really only 2 cases and if you know what to do its not that bad.

the main drawback of 2 at a time is a higher move count, as well as finding pieces always seemed harder to me, with 10 possible spots all over instead of just looking on the U/D or L/R face

so the big thing to remember is try everything and see what works best for you, none of these methods is necessarily better than the other

(except cage, which doesn't count )

I'm working on two at a time. It's a struggle for me. Hopefully it'll become second-nature after more practice...

When in the solve do you spot out the parities? And do you prefer to do (when there's more than one) one case before the other (ie: switching the two corners, THEN switching opposite edges/flipping one edge, vice versa, etc)?

I used to spot the OLL Parity at OLL and the PLL parity at PLL.....

Ah, yeah me too. That was kind of a stupid question.

But is there any preference as to switching corners or switching edges first? Do you fix them before doing PLL or after?

i do f2l then if i see 1 or 3 edges correct i do the oll double parity (faster for execution and still 50% chance of pll parity) if i can tell there is no pll parity (which is pretty rare) then i'll use the regular parity. after the top is oriented, i look to see if i recognize the perm, if i don't, then i immediately to the pll fix (no targeting needed) then normal pll.

if you want to work on your recognition maybe start by trying to pair up the yellow/white edges because they are easiest to see, then when you get comfortable remove the restriction.

ps-pembo don't sound like that was the obvious answer i used to do oll parity after completing step 3 in petrus, and there are a number of alternatives to doing them at the very end.

When I used centers/edges/3x3, I only learned one PLL (Opposite edges) and just used that before applying the PLL.

As for me, I know only one OLL parity and only one PLL parity, and so as soon as I see any parity at all I just use the algorithm I know. So my last layer looks like this: OLL parity, OLL, PLL parity, PLL. It seems the most natural that way.

However, I've lately been considering finding and learning an OLL parity algorithm that flips exactly 3 edges. That way, if you have OLL parity, you will always have the edges correctly flipped after the algorithm, so you can then do corner orientation/PLL or CLL/edge permutation to finish.

(Does anyone know a reasonably fast algorithm to flip three LL edges and keep the F2L?)

i have a ton, most are combinations of setup moves and parity fixes, let me knwo fi there is a prticular corner postition you're interested in otherwise i'll mae a sheet and post it i guess.

oh screw it i'll just post it

Thanks! (Can you thank Michael for me? I don't have his contact.)

Here's what I think I'll be doing: hold the correctly oriented edge on R and go
B’ R’ [(Rr)2 B2 U2 (Ll) U2 (Rr)' U2 (Rr) U2 F2 (Rr) F2 (Ll)' B2 (Rr)2] R B.

I only really need one alg, and this is probably the best one there for me. But, again, thank you for the table!

hey no problem, i use the same setup move, but with the double parity alg instead, you should try it since you have it there its much faster exectution than normal parity, if you do a R' cube rotation before the B's

l'U2 l'U2 x U2l' U2r x' U2r' U2l2 is a good parity alg for when you don't pair. Swaps opposite edges without disturbing centres.

This is how it effects centres on a supercube:

Is this right? I don't have a supercube.

I can't get it to work correctly. Can you write out what you mean in terms of the turns involved?
