2. 〇〇〇〇●●●● The model of solving 3W3B may misguide you to solve 4W4B. Unlike ‘3’, the moving pieces of 2 nd displacement are moved to the vacant position after the 1 st displacement. 〇 〇〇 〇●●●● 〇 〇 ●● ●●〇〇 〇●●〇 ● ● 〇 〇 ● 〇●〇●〇●〇 1 st displacement Initial arrangement 2 nd displacement 〇● ●〇●〇● 〇 3 rd displacement 4 th displacement Underline denotes moving pieces 下划线表示移位子 ‘ 3’ 的解题模式可能会误导你求解‘ 4’ 。同解‘ 3’ 不一样，第 2 次移位子是移向上次移位后出现的空位。

3. 〇〇〇〇〇●●●●● 〇〇〇〇〇〇●●●●●● 〇〇〇〇〇〇〇●●●●●●● 〇〇〇〇〇〇〇 … 〇● … ●●●●●●● Can 5W5B be solved by 5 displacements, 6W6B be solved by 6 displacements, …and n B n W be solved by n displacements, no matter how great the number n is? The answer is yes . 5 白 5 黑移位 5 次， 6 白 6 黑移位 6 次，… n 白 n 黑移位 n 次，不论 n 有多大都能获解吗？ 回答是 能 。 Continued in part 3 www.slideshare.net/zhpei
