Hi there, take a look at my cube solver: [My trial to make a mapping of (2x2x2 rubik’s cube, poket cube, mini cube)’s states with solutions.Recursive function wanted.](https://discourse.julialang.org/t/my-trial-to-make-a-mapping-of-2x2x2-rubiks-cube-poket-cube-mini-cube-s-states-with-solutions-recursive-function-wanted/9726)  
I know it is a bit messy haha…  
You could only use 7 numbers in `cp` and `co` it is sufficient to describe the cube, but not much difference.Message me if you are interested.
