This group, sometimes denoted and sometimes denoted , is defined in the following equivalent ways:
- It is the dicyclic group (i.e., the binary dihedral group) of order , and hence of degree .
- It is the binary von Dyck group with parameters .
A presentation for the group is given by:
.
GAP implementation
Group ID
The group has ID among the groups of order . Hence, it can be defined using GAP's SmallGroup function:
SmallGroup(12,1)
Other definitions
The group can also be defined using its presentation:
F := FreeGroup(3); G := F/[F.1^3 * F.2^(-2), F.2^2 * F.3^(-2), F.1 * F.2 * (F.3)^(-1)];
