Definition

This group is defined as the external direct product of symmetric group:S4 and cyclic group:Z4.

Arithmetic functions

Function Value Similar groups Explanation
order (number of elements, equivalently, cardinality or size of underlying set) 96 groups with same order order of direct product is product of orders, so the order is $24 \times 4$ where $24 =4!$ is the order of symmetric group:S4 and $4$ is the order of cyclic group:Z4.
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, so the exponent is $\operatorname{lcm}\{12,4\} = 12$.
minimum size of generating set 2 groups with same order and minimum size of generating set | groups with same minimum size of generating set

GAP implementation

Group ID

This finite group has order 96 and has ID 186 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:

SmallGroup(96,186)

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

gap> G := SmallGroup(96,186);

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

IdGroup(G) = [96,186]

or just do:

IdGroup(G)

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