Group ID

This finite group has order 56 and has ID 5 among the groups of order 56 in GAP's SmallGroup library. For context, there are groups of order 56. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(56,5)

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

gap> G := SmallGroup(56,5);

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

IdGroup(G) = [56,5]

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 defined using GAP's DihedralGroup function:

DihedralGroup(56)
