In how many different ways can six kings be placed on a 6x6 chessboard so
that no one attacks the others?
If the problem was asked for a 3x3 board and 3 kings, then the answer would
be 8.
在一個 6x6 的西洋棋盤上放入六個國王使其不互相攻擊有幾種放法?
若題目改問 3x3 的棋盤及三個國王則答案為8。

又是以前出過題目的推廣題 (2012 Q4 #1GAyHf0z)
翻譯也只要抄過來改幾個字就好 XD
不過六個王果然不能用手算了嗎...(思)
