This article is about a family of groups with a parameter that is prime. For any fixed value of the prime, we get a particular group.

Definition
Let be a prime number. This group, denoted or , is defined as the elementary abelian group of order . Equivalently, it can be defined in the following equivalent ways:
- It is the external direct product of four copies of the group of prime order.
- It is the additive group of the four-dimensional vector space over the field .
Particular cases
| Value of prime number | Value of | Elementary abelian group of order |
|---|---|---|
| 2 | 16 | elementary abelian group:E16 |
| 3 | 81 | elementary abelian group:E81 |
| 5 | 625 | elementary abelian group:E625 |
GAP implementation
The group can be constructed using the ElementaryAbelianGroup function as ElementaryAbelianGroup(p^4).
