Notes on the length of conjugacy classes of finite group. II. (Chinese. English summary) Zbl 1488.20050

Summary: We investigate the influence of the lengths of conjugacy classes of elements of prime power order in some factorized finite groups on \(p\)-nilpotence and supersolvability of finite groups. Several results are improved.
