The Rubik's Cube can be mathematically formulated as a permutation problem. The cube can be represented as a 3D array of size nxnxn, where each element represents a sticker on the cube. The goal is to find a sequence of moves that transforms the cube into a solved state. import numpy as np class NxNCube: def __init__(self,

| Patch type | Example fix | |------------|--------------| | | OLL parity fix for 4x4x4 and 6x6x6 when reduction fails. | | Performance | Replace recursion with iteration in center solving. | | Memory | Use array('H') instead of Python lists for move tables. | | Visualization | Fix print_cube() for N>5 (alignment issues). | | Scramble generator | Patch random move sequence to avoid inverse cancellations. | | Algorithm correctness | Correct commutator for last two centers on odd N. | The goal is to find a sequence of
