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

Facts

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.
