补充资料：排列
| 排列 permutation 组合数学的基本概念，从有限个元素中取出全部或一部分按照一定的顺序排成的一个系列。例如3个数码1，2，3全部取出可以作成6个不同的排列：123，132，213，231，312，321。在组合数学中，常要研究由指定的一组元素中每次取出一定数量的元素来作排列 ，一共能作多少个不同的排列，用符号P  表示从n个不同的元素中任意取出m个元素所作的不同排列的总数，那么有公式P  ＝n（n－1）（n－2）…（n－m＋1），称为排列数公式。当m＝n时，称为全排列，全排列数公式为P  ＝n（n－1）（n－2）…2·1＝n！。记号n！表示从1到n这n个自然数的连乘积，称为阶乘。 |
