1·1. A group is called characteristically simple if it has no proper non-trivial subgroups which are left invariant by all of its automorphisms. One familiar class of characteristically simple groups consists of all direct powers of simple groups: this contains all finite characteristically simple groups, and, more generally, all characteristically simple groups having minimal normal subgroups. However not all characteristically simple groups lie in this class because, for instance, additive groups of fields are characteristically simple. Our object here is to construct finitely generated ...

1. A group G is called characteristically simple if it has no proper non-trivial subgroups which are invariant under all automorphisms of G . It is known that if G is characteristically simple then each countable subgroup lies in a countable characteristically simple subgroup of G . A similar assertion holds for simple groups. These results were proved by Philip Hall ... further proofs appear in (4) and (6). For simple groups there is a well known and elementary ... subgroup of a group G lies in a simple subgroup, then G is simple. These considerations prompt ...
