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? 你有八個一模一樣的單位立方體，每個都標一個各不相同的字母。這八個立方體合成一個2x2x2的立方體。依照以下的方式得出一個八字母的字串： ‧ 從任一個單位立方體做為起點； ‧ 每次移動可以到達相鄰的立方體 (即共面的立方體)； ‧ 要經過八個立方體正好一次。試問如此一來能夠得到多少種字串？ -- 又有種熟悉感... -- LPH [acronym] = Let Program Heal us -- New Uncyclopedian Dictionary, Minmei Publishing Co. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.230.62
