1) What is a good alg for the 2 edge swap on 4x4 (not parity, but where there are 2 unpaired edges)?

2) What is the main difference between a ShengShou 4x4 v4 and a v5? (Structural)

3) The inner layers on my 4x4 turn awesomely but the outer layers catch a lot and lock up like crazy. How do I resolve this? Should I adjust the tensions?

3) Is it new? It might need some breaking in (lockups reduced on my SS4 v4 after breaking in. If you've already broken it in, then tension it between an eighth and a quarter turn tighter. Repeat until ideal tensions set.

I had lubed my cube with silicone spray, but it left residue on the faces that won't come off. What should I do?

On the Maru 4x4 V2 did they Fix the middle layer misalignment issue of the V1 4x4? Also what are the other changes? Is there a video comparing the 2 4x4s?

Thanks ...3) I just got it day before yesterday and have done 10-15 solves on it.. so I will try breaking it in for a week or two.

Don't worry about it, keep breaking it in and don't lube it with the same spray if you're concerned about the white stuff. Try other lubes.

Which viscosity is good for large cubes (SS 4x4 and 5x5 in this case)? I use 65k for my 3x3 but I read that lighter lubes are better for bigger cubes.

50k, or Lubix

When it's about popping, what is calculated as DNF? 3 or more pieces pop or what?

A maximum of 4 pieces can be removed at the end of the solve if it is unsolvable. Regulation 5b3b

if the pieces can only be put back into the solved position, then its solved:

0 on 2x2
1 on 3x3 (centre cap)
5 on 4x4
10 on 5x5
18 on 6x6
27 on 7x7 (but 24 of them have to be 1 whole centre, and the other 3 have to be an inner wing and an outer wing and a centre cap)

edit:

which is \( N^2-\frac{7N}{2}+4+\frac{3(\text{cos}(N\pi)-1)}{4}-(N+1)(\text{mod 2}) \) on an NxN rubix cube i think

Was this used to determine the answer or was there a general number and this equation formalized it?

I counted the amount of pieces for 2x2-7x7 then worked out the formula separately

 

[TheNextFeliks]

Is one 4x4 edge pop considered to not be a DNF cause you can only put it one way?

 

[JohanAR]

\( N^2-\frac{7N}{2}+4+\frac{3(\text{cos}(N\pi)-1)}{4}-(N+1)(\text{mod 2}) \) on an NxN rubix cube i think

Same as \( x(1+3x)/((1+x)(1-x)^3) \) ?

 

[stoic]

I thought you could have up to 3 centres missing on a solved 3x3 (depending on which ones) and its still solved?

 

[Renslay]

Consider that there is an evil guy who try to put your popped pieces back in the wrong way.
If he could not do that, then your solution is correct. Otherwise, it is DNF through the pop.
So, in a 3x3x3, if you finish your solving with one center piece popped, then your solution is valid. But with two popped pieces, it is not (the evil guy can put those centers back in the wrong way).

On a 4x4x4, you can have 4 popped centers with the same color(!), and one edge. Because the evil guy can assemble your cube in only one way, and it would be the solved state.

"5b5) If parts of the puzzle are still defective or not fully placed at the end of the attempt, the result is recorded as the worst state obtainable by repairing the puzzle (see Regulation 5b3)."

 

[JohanAR]

I think this question could be interpreted in 2 different ways; "How many pieces can be popped when the timer is stopped", or "how many pieces can be popped during the solve and reinserted while timer is still running".

Dan Cohen has good ones. With a good recog system.

Does anyone know any good tricks for when you have two cross edges flipped in the u face opposite each other? I just do like R' F R L' B L
