7x7 Edge Pairing

[dude_500]

Are there tutorials on more advanced methods? I do one edge piece at a time and it takes me 10+ minutes to pair all 12 edges. I've seen people do crazy stuff on youtube to pair a whole edge set in 10 seconds but I can't follow what's going on.

A lot of people use whats call multi-reduction. Basically what you do is do 5x5 edges twice(center three edges first then then finish the outside edges).

If your 5x5 method is one piece at a time I suggest learning a new method like AvG, freeslice etc.

5x5 Edge Pairing Tutorial That's what i do for 5x5 edges. It's the same for the 7x7 edges. Just instead of finding 3 pieces, you find 5. For the last 4 edges i do multi-reduction. Where i pair the middle 3 pieces like a 5x5, this reduces the last 4 edges on the 7x7, to the last 4 edges on the 5x5. Than i finish them off, and bam! Straight onto 3x3.

A little off topic...but if I know how to solve a 4x4, do I pretty much know how to solve a 5x5, 6x6, and 7x7 as well?

If you know how to solve a 4x4 you know all the algorithms needed to to sovle any sized cube. Just play around with it, you'll get it.

Sweet. My V-Cube set is supposed to arrive tomorrow so I'm pretty excited.

I'm not sure if that's true. There is one algorithm for the 5x5 that I had to learn to solve that I didn't learn from the 4x4.
On the last two edge segments if you only need to switch out two edges:
L'* 2U L'* 2U 2F L'* 2F R* 2U R'* 2U 2L*

(The eighth animation on this page: http://bigcubes.com/5x5x5/lastedges.html)

That same algorithm is applicable on the 7x7 edges.

All of those cases can be solved using parity and the first algorithm(which is also a 4x4 algorithm).

I'm having quite a bit of trouble with the centers on these bigger cubes...

I must be dumb.

 

[trying-to-speedcube...]

centers of the 6x6+ cubes are indeed a bit different, but they are easy once you learn one move. just check youtube for "how to solve last 2 centers on any big cube" or something like that.

edit: here is the link: http://www.youtube.com/watch?v=cVDdHmHGRB8&feature=related

@dude_500: the method I use for 7x7, (don't have the v-cube yet but avg 12 minutes on gabbasoft with no lookahead whatsoever what should easily result in a sub-10 avg with the real cube) I just search a piece, put it into the middle layers(I like to have between U and D, but between L and R should work too) (DO NOT CHANGE THE ORIENTATION OF THE CENTERS!!!!!)and pair it up with the same color piece, I search for the next one and pair it up, search for the next one etc. when an edge is done (in your middle slice the centers should be cut in stripes of 5x1) put it into the storage area (U and D). when your storage area is full fix the centers. you should now have centers fixed, and 8 edges done. then I solve the middle 3 layer edges 5x5 style, then the rest 5x5 style. tada!

No, not at all. It can be quite tricky in the beginning.
But once you got it, it pretty easy and fast.

Grab yourself a solved 5x5 and do:

Rw R' U'
Lw' L U
Rw' R U'
Lw L' U

To exchange these two pieces, you do
F (then the alg above) and F'

Hope you saw what you need to do.
Note: the F is only to put the two centre pieces in the same position on the centre and the last U and the F' are just to restore everything, don't bother about these in an actual solve.

ok, i hope this made sense.
if there are any questions, don't hesitate

btw: i think this is a simple commutator, but i'm not sure.

I think I know what you mean. I've been messing around with my 5x5 a little bit more and I'm starting to get the hang of it. I guess it's just like when I started 4x4. It seemed so hard at first but now 4x4 is really simple.

As for the example you posted, I'll have to get back to you about that tonight. I'm in a computer lab and don't want to bring to much attention to myself.

Edit: And sorry for taking this thread a bit off topic.

Remember: cubers aren't dumb!

 

[DavidWoner]

yeah its the same idea but it takes more getting used to. I solved my first 6x6x6 today and I could figure out everything except fot how to switch two outer center edges. Then Ellery showed me the trick, its not obvious, but you can understand it once you see it. Edges took me a while also, it was rather hard to do face turns, and I used freeslice instead of double edge pairing. I think double edge pairing would have been faster.

Wow, that helped a lot. Thanks. But what if the last center cube is in another spot than the one you posted?

How do you swap two individual edge pieces.
R L
R L
R L
R L
L R
R L
R L

 

[masterofthebass]

just like 5x5. it seems like you have parity on the inner wings.

 

[mrCage]

This alg will get you sorted, both for pairing up and and last layer parity:

l' U2 l' U2 F2 l' F2 r U2 r' U2 r U2 l2

Substitute l and r moves with moves on the layer depth you want to work on Dumb, but it works like a charm:rolleyes:
