Because the inverse of Lagrange theorem of finite group is not hold,it is difficult to determine all the subgroups of A_n,to determive whether An has the same order subgroups for any positive factor of the absolute value of |An|.
由于有限群的L agrange定理的逆不成立,当n较大时,要确定n次交代群An的所有子群,以及对于An的任一正因数,要确定A n是否有这个阶数的子群都要较困难的,文章通过计算5-循环置换各次方幂,再把各次方幂中的第4个数字去掉,得到4个2×2置换的乘积,从而构造出A 5的6个10阶子集,并证明了每个子集是A5的子群。
