Verified: Nxnxn Rubik 39scube Algorithm Github Python

: Breaks the problem into four sub-groups, reducing the search space progressively. Many Python solvers, such as itaysadeh/rubiks-cube-solver , implement this to achieve solutions in fewer than 52 moves.

Every stage's move set is proven to reduce the cube to the next subgroup (G1 → G2 → G3 → solved). The code checks that after each phase, the cube belongs to the correct subgroup using invariant scanning. nxnxn rubik 39scube algorithm github python verified
