论文摘要
魔方是一个著名的难题，可以移动面孔，相应的运动操作定义了一组。我们在这里考虑对任何$ 3 $价值地图的概括。我们证明了对相应组的大小的上限，我们猜测是紧密的。
The Rubik's cube is a famous puzzle in which faces can be moved and the corresponding movement operations define a group. We consider here a generalization to any $3$-valent map. We prove an upper bound on the size of the corresponding group which we conjecture to be tight.
