7x7 — Cube Solver

Leo watched the move counter. It was climbing rapidly. 50 moves. 100 moves. A human solver would take about 400 to 600 moves. Goliath was trying to do it in under 200. The optimal solution.

EXECUTING FINAL ALGORITHM.

Odd-layered cubes (7x7) have a possible parity error at the end of edge pairing: one edge triplet may be flipped. Fix with a 15-move algorithm: (2R U2) * 4 etc. 7x7 cube solver

Since brute-forcing a 7x7 is computationally impossible, solvers use : Leo watched the move counter

When two edge groups need to be swapped, but the rest of the cube is solved. 7x7 cube solver
