Definition
Symbol-free definition
An elementary Abelian group is a group that satisfies the following equivalent conditions:
- It is an Abelian characteristically simple group
- It is a direct product of isomorphic subgroups, each being cyclic of prime order
- It is the additive group of a vector space over a prime field

Minimal normal subgroups
Any minimal normal subgroup in a solvable group must be elementary Abelian. This follows by combining the fact that it must be Abelian with the fact that in any group, a minimal normal subgroup is always characteristically simple.
