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:

  1. It is the external direct product of four copies of the group of prime order.
  2. It is the additive group of the four-dimensional vector space over the field .

GAP implementation

The group can be constructed using the ElementaryAbelianGroup function as ElementaryAbelianGroup(p^4).
