## Definition

A group is termed a group generated by finitely many periodic elements if it satisfies the following equivalent conditions:

1. It has a generating set that is finite and comprises elements only of finite orders.
2. It is both a finitely generated group and a group generated by periodic elements (this definition is a priori different from the first one in that we are not assuming that the finite generating set and the generating set comprising periodic elements are the same).
3. It is a join of finitely many finite subgroups.
4. It is a join of finitely many finite cyclic subgroups.

finite abelian group abelian group See also equivalence of definitions of periodic abelian group: this shows that for an abelian group, being generated by periodic elements is equivalent to being locally finite, which in turn means that if it is also finitely generated, it is finite.
finite nilpotent group nilpotent group See also equivalence of definitions of periodic nilpotent group: this shows that for a nilpotent group, being generated by periodic elements is equivalent to being locally finite, which in turn means that if it is also finitely generated, it is finite.
