interesting solve method for 7x7x7

[panyan]

we solve the 7x7x7 by equating it to the 3x3x3 in the following way:



but would it also be possible to solve it in the way depicted below?



if we took this even further, could it be solved with the following method?



the way the numbers work is like this (in relation to the images above):



I AM IN NOW WAY LOOKING FOR A FLAMING, THIS IS PURELY FOR DISCUSSION

Yes, it could, but the nature of the pieces makes reducing it to such groups very difficult.

Yea, it's kind of like trying to solve a 4x4 like a 2x2. It sounds nice, but it usually isn't a good speedsolving method. I don't own a 7x7 though...

Effective: Hell no
Fun and annoying: Yep

I love solving stuff this way, although it takes me the best of 10 minutes to redux a 4x4 into a 2x2

hey, i didnt say anything about this being effective, i just thought it would be interesting to share

For the 4x4, use slice turns to match up the centers, then 3 cycle the edges untill a 2x2. I've never tried it, but I might be able to get sub-10.

I suspect a "reason" why this kind of reduction is hard is that you're building 3-dimensional blocks. Note that the normal reduction only builds 2-dimensional blocks. Each 3-dimensional one is harder to build and harder to maintain, especially the last ones.

It may be good for FMC though.

Building a 3x4 block is a bit difficult.

i agree, thats why this is posted in "puzzle theory", not the speedsolving bit

But it's not really puzzle theory, not even because of that. I'm actually moving this thread.

Anyhow, the overwhelming consensus on this among people who have some idea about methods is that it's highly impractical if you try it.

Who does FMC for anything other than 3x3x3?

01:00:25 <%PatrickJameson> because anything difficult is automatically puzzle theory

the whole point of this thread is that it is something interesting and not to be taken as an actual method for solving (because of its immense impracticality), which is why i didnt post it in the speedsolving section, but, seeing as your a super mod, do as you see fit.

I agree. It IS interesting.
Now apply it to the 11x11x11 XD

get me one and ill be glad to
