Much as every integer can be broken down into a product of prime Numbers, the symmetries of any object can be constructed from a collection of basic building blocks known as simple groups.
正如每个整数都可用一些质数的积表示，任一对象的对称都可由所谓简单群的基本构件集合构造出来。

You could also write code that USES a positive integer's factors to determine if it is a prime number (defined as an integer greater than 1 whose only factors are 1 and the number itself).
