◆CUBE TRAVEL
http://www.puzzleup.com/2015/img/puzzle/2015/09.jpg
You will make a travel through the edges of two cubes connected by their
vertices as shown in the figure.
- You will start on A, and finish on B.
- You can pass through the vertices more than once except the finishing
vertex B.
- You can't pass through the edges more than once.
In how many different ways can this travel be done?
Note: Two travels having same edges in different order will be considered as
different.
你將從上圖這兩個立方體在一個頂點相接的圖形的邊上進行移動。
- 路線從 A 開始,到 B 結束。
- 除了 B 之外的任一頂點皆可以經過多於一次。
- 任一條邊不能經過多於一次。
試問如此的移動有多少種不同的走法?
注意: 兩個走法若僅是經過的邊順序不同依然視為不同走法。
