Abstract:In this paper the subgroup-closed saturated Fitting formations of radical locally finite groups with min-p for all p are fully characterised. Moreover the study of a class of generalised nilpotent groups introduced by Ballester-Bolinches and Pedraza is continued.
“…It has been studied extensively in [1,2,3]. This class is intermediate between nilpotent and locally nilpotent groups, and it is the natural generalisation of the class of finite nilpotent groups from the finite universe to the universe cL.…”
Radical locally finite groups with min-p for all primes p in which every descendant subgroup is normal are studied in the paper. It turns out that these groups are precisely Tgroups, that is, groups whose subnormal subgroups are normal.

Radical locally finite groups with min-p for all primes p in which every descendant subgroup is normal are studied in the paper. It turns out that these groups are precisely Tgroups, that is, groups whose subnormal subgroups are normal.
This paper is devoted to the study of a class of generalised p-nilpotent groups in the universe cC of all radical locally finite groups satisfying min-g for every prime q. Some results of finite groups are extended and a characterisation of the injectors associated with this class is given.
