This group is defined in the following equivalent ways:
- It is the central product of dihedral group:D8 and the quaternion group over a commonly identified cyclic central subgroup cyclic group:Z2.
- It is the extraspecial group of order and type .

|group of prime power order||Yes|
|nilpotent group||Yes||prime power order implies nilpotent|
|supersolvable group||Yes||via nilpotent: finite nilpotent implies supersolvable|
|solvable group||Yes||via nilpotent: nilpotent implies solvable|
|extraspecial group||Yes||Hence also satisfies property special group, group of nilpotency class two, UL-equivalent group, metabelian group.|
This finite group has order 32 and has ID 50 among the groups of order 32 in GAP's SmallGroup library. For context, there are 51 groups of order 32. It can thus be defined using GAP's SmallGroup function as:
For instance, we can use the following assignment in GAP to create the group and name it :
gap> G := SmallGroup(32,50);
Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:
IdGroup(G) = [32,50]
or just do:
to have GAP output the group ID, that we can then compare to what we want.
