Tóm tắt

In the present article we consider infinite locally finite perfect groups that are product of proper normal soluble subgroups of derived length at most n ( $$\Pi {\mathfrak {S}}_n$$ -groups for short) for some fixed positive integer n and give structural results for these groups. Also we provide some consequences for certain locally finite minimal non- $${\mathfrak {X}}$$ -groups for some classes $${\mathfrak {X}}$$ and barely transitive groups in the context mentioned above. Furthermore, we define certain collections of groups and consider their intersection with $$\Pi {\mathfrak {S}}_n$$ . Finally, we investigate some groups which have non-trivial minimal non- $${\mathfrak {FC}}$$ epimorphic images.
