◆Eight Cubes
You have eight identical unit cubes, each of which is given a different
letter. These eight unit cubes are conjoined to form a 2x2x2 cube. You will
move on these cubes and produce 8-letter codes.
‧ You can begin your tour on any unit cube.
‧ You can pass from that cube to any of the neighboring (ie. cubes sharing a
common surface) cubes.
‧ You will visit each unit cube exactly once.
How many different codes you can produce?
你有八个一模一样的单位立方体,每个都标一个各不相同的字母。
这八个立方体合成一个2x2x2的立方体。
依照以下的方式得出一个八字母的字串:
‧ 从任一个单位立方体做为起点;
‧ 每次移动可以到达相邻的立方体 (即共面的立方体);
‧ 要经过八个立方体正好一次。
试问如此一来能够得到多少种字串?
