首先是强烈推荐hht的bolg：http://techotaku.lofter.com/post/4856f0_59d4957
感觉看了之后群论就有了概念了啊!
至于细节方面，可以参考这篇blog：

一些要点我还是写一写，免得以后忘了吧：
1）因为Polya只能解决不限使用次数的染色问题，所以Burnside也是有用的
2）Burnside用的是不动点的个数，Polya用的是置换的循环节
3）很多题目，给出的置换，不足以组成一个置换群，所以要先补足置换群
其实一些比较难的题都还没有做，比如:BZOJ_1488
所以，以后还要花时间再做一次专题才行啊！
另外，定理的证明还一点都不会，只能留到下一次专题一起做了吧！
Heya i’m for the first time here. I found this board and I find It really useful & it helped me out a lot. I hope to give something back and help others like you aided me.
obviously like your web-site but you need to check the spelling on several of your posts. Several of them are rife with spelling problems and I find it very troublesome to tell the truth nevertheless I will certainly come back again.
