[Help Thread] 3x3 picture cube on a 5x5

[Deleted member 36445]

I want to make a picture cube on a 5x5
Like this one

My idea is to swap centers around like this

I managed to swap some centers but I can't go on without messing the rest.

 Twizzle link 

((U' 2R U' M' U 2R' U' M U2 y)4 z2)2

Can anyone help?

U know one of the algs for 5x5 to swap 2 Center pieces?

Yes look what I posted on the twizzle visualization

But when i proceed to the e-slice I mess up the other centers

Because you're not straight swapping two centers but it's a 3cycle

Try this:
U2 F2 D R2 B2 D R2 F2 U2 B2 L' R' F' D' B2 F2 D R2 F2 U' Fw2 Rw2 F2 D2 R2 Bw2 Lw2 U Bw2 D2 Rw2 Dw2 Bw2 Rw2 Uw2 B Rw2 B2 Rw2 Fw2 L2 Uw2 L2 B R L U R2 Rw Lw D U Rw Lw F B Rw Lw Bw Fw Dw Uw Fw Bw
Quite long but it should work

 

[Lio2010]

Yep it does

Try this:
U2 F2 D R2 B2 D R2 F2 U2 B2 L' R' F' D' B2 F2 D R2 F2 U' Fw2 Rw2 F2 D2 R2 Bw2 Lw2 U Bw2 D2 Rw2 Dw2 Bw2 Rw2 Uw2 B Rw2 B2 Rw2 Fw2 L2 Uw2 L2 B R L U R2 Rw Lw D U Rw Lw F B Rw Lw Bw Fw Dw Uw Fw Bw
Quite long but it should work

thanks it works!
can you explain what the heck is going on?

another question, how to do that pattern on 6x6, 7x7 and up?

5-phase reduction.

Bw' Fw' Uw' Dw' Fw' Bw' // LR centres
Lw' Rw' B' F' Lw' Rw' U' D' Lw' Rw' // other centres
R2 U' L' R' B' L2 Uw2 L2 Fw2 Rw2 B2 Rw2 B' // EO, FB centres half-turn-solvable
Uw2 Rw2 Bw2 Dw2 // E-slice tredges, LRFB centres in columns
Rw2 D2 Bw2 U' Lw2 Bw2 R2 D2 F2 Rw2 Fw2 // finish reduction
U F2 R2 D' F2 B2 D F R L B2 U2 F2 R2 D' B2 R2 D' F2 U2

(Almost looks like what my solver would spit out… except mine preferentially uses clockwise turns over anticlockwise turns so maybe not? Maybe it's Chen Shuang's solver instead (similar algorithm).)

edit: A shorter alg (45 OBTM):

U L F L2 D R D B D2 L
M2 S2 E2
L' D2 B' D' R' D' L2 F' L' U'
r b l f d l r' b2 f d' u l d' u r' d' f' r' u'

thanks guys!

that really helped.

by the way @xyzzy , that alg was found with Chen Shuang's solver?

 

[xyzzy]

The 45-move one was found by my brain + Cube Explorer.

The first line flips six edges (10-move alg found with Cube Explorer); the first three lines is a partial commutator for flipping all 12 midges; the last line is superflip combined with checkerboard (19-move alg from Cube Explorer's website).

edit: I don't know anything about the origin of the longer one. It's probably not mine.

How could this be possible on high order cubes, if you don't take corner-like center into consideration?

ok so, I just noticed that it works in any order of cube larger than 4x4!
