Definition

This group is the dihedral group of order 24.

GAP implementation

Group ID

This finite group has order 24 and has ID 6 among the groups of order 24 in GAP's SmallGroup library. For context, there are 15 groups of order 24. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(24,6)

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

gap> G := SmallGroup(24,6);

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

IdGroup(G) = [24,6]

or just do:

IdGroup(G)

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

The group can be defined using GAP's DihedralGroup function:
