N2 - Let σ = {σi | i ∈ I} be a fixed partition of the set of all primes into pairwise disjoint nonempty subsets σi. A finite group is called σ-nilpotent if it has a normal σi-Hall subgroup for any i ∈ I. Any finite group possesses a σ-nilpotent radical, which is the largest normal σ-nilpotent subgroup. In this note, it is proved that there exists an integer m = m(σ) such that the σ-nilpotent radical of any finite group coincides with the set of elements x such that any m conjugates of x generate a σ-nilpotent subgroup. Other possible analogs of the classical Baer–Suzuki theorem are discussed.
