给出了非循环子群共轭类个数为5的有限幂零群的分类.由此,对非循环子群共轭类个数不大于5的有限幂零群进行了完全分类.
The finite nilpotent groups with 5 conjugacy classes of noncyclic subgroups are completely classified,from which one can give the structure of all finite nilpotent groups with the number of conjugacy classes of noncyclic subgroups at most 5.
