Does someone have a 2-gen algorthim for the Y perm. The 2 faces are R and U?
U r U r' U' r U' r' y' R x' U' R2 U R' x U' R2
this alg uses R U an r moves (which is the 2 right layers)
it also uses the x and y rotations, without these, an RUr
solution is not possible.
It is possible to have an RUu solution without y rotations,
leaving only the x rotation wich is almost an R turn while
releasing the other hand
x U R x' U' R' U' x2 R u R x2 U R' x' U' R x U' R2
