      The 3x3 Domino example solve Game!

      This thread is for example solves for scrambles that use half turns (R2, L2, F2, B2) except for the U and D moves. This is related Domino reduction from FMC. Try to solve using the restricted moves as well, except for the PLL alg at the end. In cstimer LxMxN > 2x3x3 Domino scrambles can be used...

      Some calculations on the PLL subgroup lattice

      I have been investigating the PLL group a bit recently. By this I refer to the subgroup of the rubiks cube permutation group which permutes the top layer only, and keeps it oriented. This includes the identity, U, U2, U', the 21 PLLs but also every U conjugation of the PLLs. How large is this...

      Why are the T Y and Jb perms related by cyclic shift?

      Is there a mathematical reason why these algorithms are so similar? T perm: R U R' U' R' F R2 U' R' U' R U R' F' Y perm: F R U' R' U' R U R' F' R U R' U' R' F R F' Jb perm: R U R' F' R U R' U' R' F R2 U' R' U' I understand the F perm is just a conjugated T perm, but I don't really know about...

      (DIY) Putting together a supercube?

      Hello It does not seem easy to buy a 4x4 supercube. I am curious about potentially creating one from an existing 4x4. I think that I prefer the Pochmann Color scheme, How hard would it be to create and sticker a 4x4? Are there guides on it or has anybody done this, and if so what was your...

      Restriction games with the cube (subgroups)

      I am solving the 3x3 cube with CFOP but I have become interesting in the following games and wanted to ask if anybody has more information about them. Solve the cube using only M and U moves after scrambling the only moves M and U. This leaves the top layer corners alone and a block of 6 on the...
