Definition

This group is defined in the following equivalent ways:

  1. It is the direct product of the elementary abelian group of order eight and the cyclic group of order three.
  2. It is the direct product of the cyclic group of order six and the Klein four-group.

Group ID

This finite group has order 24 and has ID 15 among the group of order 24 in GAP's SmallGroup library. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(24,15)

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

gap> G := SmallGroup(24,15);

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

IdGroup(G) = [24,15]

or just do:

IdGroup(G)

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


Other descriptions

The group can be constructed using GAP's DirectProduct, ElementaryAbelianGroup, and CyclicGroup functions:

DirectProduct(ElementaryAbelianGroup(8),CyclicGroup(3))
