解法一:                                                                                                                                    原解法方向正確,但因首先入座者可改變座位,成為不同的坐法,故整個問題的解為                                                                                                                                                   8!2!-7!2!2!=7!2!× 6                                                                                                  解法二：

將夫妻二人看成一人與不受限制的5人及不和中任一人任意入座有7！坐法.在一起的夫妻2人有2！坐法,不和2人中另一人入座上述任一坐法，但與不和者分開，有6種坐法,故總共有7！2!×6種坐法.
