This group is defined in the following equivalent ways:
- It is the external direct product of alternating group:A4, cyclic group:Z4, and cyclic group:Z2.
- It is the external direct product of alternating group:A4 and direct product of Z4 and Z2.
- It is the external direct product of cyclic group:Z4 and direct product of A4 and Z2.
- It is the external direct product of cyclic group:Z2 and direct product of A4 and Z4.

|order (number of elements, equivalently, cardinality or size of underlying set)||96||groups with same order||order of direct product is product of orders: the order is , where is the order of alternating group:A4, 4 is the order of cyclic group:Z4 and 2 is the order of cyclic group:Z2.|
|exponent of a group||12||groups with same order and exponent of a group | groups with same exponent of a group||exponent of direct product is lcm of exponents: the exponent is .|
|minimum size of generating set||2||groups with same order and minimum size of generating set | groups with same minimum size of generating set|
|derived length||2||groups with same order and derived length | groups with same derived length||derived length of direct product is maximum of derived lengths: the derived length is thus .|
This finite group has order 96 and has ID 196 among the groups of order 96 in GAP's SmallGroup library. For context, there are 231 groups of order 96. 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(96,196);
Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:
IdGroup(G) = [96,196]
or just do:
to have GAP output the group ID, that we can then compare to what we want.
