For a finite group G , let ψ ( G ) denote the sum of element orders of G . If n is a positive integer let C n be the cyclic group of order n . It is known that ψ ( C n ) is the maximum value of ψ on the set of groups of order n , and ψ ( G ) = ψ ( C n ) if and only if G is cyclic of order n . In this paper, we investigate the second largest value of ψ on the set of groups of order n and the structure of groups G of order n with this value of ψ ( G ) when n is odd.

奇数组中元素阶的总和
对于有限群G , 让ψ ( G ) 表示元素阶数的总和G . 如果n 是一个正整数C n 是有序的循环群n . 众所周知ψ ( C n ) 是最大值ψ 在有序组的集合上n , 和ψ ( G ) = ψ ( C n ) 当且仅当G 是有序循环的n . 在本文中,我们研究了ψ 在有序组的集合上n 和组的结构G 有秩序的n 与这个值ψ ( G ) 什么时候n 很奇怪。
