Barely transitive groups. (English) Zbl 1139.20034
A group $$G$$ has a barely transitive representation if $$G$$ acts on an infinite set $$\Omega$$ transitively and faithfully and every orbit of every proper subgroup is finite. A group is called a barely transitive group if it has a barely transitive representation. This paper is a survey on barely transitive groups; it also involves some recent results in the case of a non-locally finite barely transitive group.
