◆CUBE TRAVEL
http://www.puzzleup.com/2016/img/puzzle/2016/10.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 visit 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.
你将从上图这两个立方体在一个顶点相接的图形的边上进行移动。
- 路线从 A 开始,到 B 结束。
- 除了 B 之外的任一顶点皆可以经过多于一次。
- 任一条边不能经过多于一次。
试问如此的移动有多少种不同的走法?
注意: 两个走法若仅是经过的边顺序不同依然视为不同走法。

写程式算好之后发现数量有点多,用笔算会很辛苦
