Definition

Let p be a prime number. The elementary abelian group of order p^3, denoted E_{p^3}, is the elementary abelian group whose order is p^3. In other words, it is (up to isomorphism) the external direct product of three copies of the group of prime order.

GAP implementation

Group ID

This finite group has order p^3 and has ID 5 among the group of order p^3 in GAP's SmallGroup library. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(p^3,5)

For instance, we can use the following assignment in GAP to create the group and name it G:

gap> G := SmallGroup(p^3,5);

Conversely, to check whether a given group G is in fact the group we want, we can use GAP's IdGroup function:

IdGroup(G) = [p^3,5]

or just do:

IdGroup(G)

to have GAP output the group ID, that we can then compare to what we want.

Alternative descriptions

The group can also be defined using GAP's ElementaryAbelianGroup function:
