第三章，考虑离散群的混沌作用。
In chapter 4, we consider the ergodic properties of group actions.
对于大量的钮扣，或节点，随着连接线段或边缘线数量的增加，系统突然从离散的断开的小群跳转到一个巨大的连接群。
For a large number of buttons, or nodes, as the number of connecting lines or edges increases, the system rather suddenly jumps from disconnected small clusters to a giant connected cluster.
第二种方法就是运用离散对数的概念。要掌握这些概念首先需要了解乘法群的概念。
The second approach is to use the concept of discrete logarithm. Understanding this concept requires understanding some properties of multiplicative groups.
