Ok so im working on my new 4x4x5.

I've used a lot of different alogarithms to solve the 3 middle layers, but when im pairing the middle edges on the last two layers im completly stuck. Does anyone have a bunch of different alogarithms that can be used to move them in between eachoter? I always seem to end up with 5 solved and 3 unsolved and no matter what i put together from previous cubes i still cant this part.

Here's a great thread for NxNxK cuboids.

Might be a foolish question but what does "E and e" actually mean? Im not familiar with the use of the letter "e" in alogarithms. Sorry for my "noobieness" :)

I believe E is a slice move in the same direction as D.

Ok so i got further multiple times but i ended up with this three times. Any easier alogarithms than starting over again to solve it? Pretty sure its very easy, but right now im running blind here ;)

Hold it like you have in the top picture, and do this: D' L2 l2 U R2 r2 U' L2 l2 U R2 r2 U' D.

Well im quite sure i did it wrong, but that fked my whole cube twise, so now im kinda lost and trying something different. Of course stuck at a new place and clueless and blind from twisting and turning for a while :)

I think this commutator will help.

Well okay, that part where top and bottom layers had one centerpiece didn't really work out, but now i cant even reach that stage of the cube.

My current way of solving it is solving the middle 6 pieces in the 3 middle layers. But when im trying to solve the last two i keep ending up with some kind of pairity that i cant seem to understand at all.

Is this puzzle considered advanced and hard? So far its been giving me a really hard time to understand. Also the post written contained alot of information im not sure i understand due to my limitations in the english language :P

Anyways, for now its the hardest puzzle i've tried and the more time i spend with it the less sense it makes. Is there anywhere that can help me to actually understand this specific cube? Or anything like it? To me it doesnt seem to have much to do with my old 3x3x4, 3x3x5 and 3x3x7. And im also struggling to see the connection to a 5x5x6.

All NxNxK cuboids are solved by one principle: the top layer, bottom layer, average layers. Try, train. At you it will turn out.

Hi Sacro, I'm not sure why you're having trouble with the centers of the top and bottom faces. In my opinion they are the easiest part of this puzzle.

R = right face; r = right slice; R2 = 180 degree face turn; etc.

For your first case:
[r2 f2 r2 f2] U [r2 f2 r2 f2] U'

For your second case:
[r2 f2 r2 f2]

These sequences aren't pure but since the 4 white and 4 yellow centers are indistinguishable it doesn't matter.

Well my main problem now is the last case, where i cant solve the centers of the 4x5s. Last two images shows what my problem is. upper right of the center is switched. No matter what i do, i always end up with that switched piece, or two L's on one side and two lines on the other.

I know this part is suppose to be easy, but it makes no sense to meat all, cause i always end up where i began.

Also those last alogarithms did nothing. One round of it made the L's and lnes, another put me back in the "one-piece swiched".

By far the most frustrating cube i have :P

I REALLY need help with a way to switch these two. Im so blind and its actually starting to become annoying. Does anyone have an alogarithm i can use?

I made two videos for you. The first is a demonstration of a simple 3-cycle. The second is a demonstration of how to use setup moves with that 3-cycle.

For what it is worth, a more generic version of this 3-cycle can cycle almost any piece on the puzzle. I use the same routine to cycle the corners, edges between two 4x5 faces, and centers of the 4x5 faces.

Thank you extremly much for that. Not my way of solving anything, so learning something new is great! I make the cube a 3x3x3, and from there solve it like a 3x3x4. Same way i solve all my odd number NxNxK.
