Function Value Similar groups Explanation
order (number of elements, equivalently, cardinality or size of underlying set) 120 groups with same order order of direct product is product of orders: the order is $24 \times 5$ where $24 = 4!$ is the order of symmetric group:S4 and $5$ is the order of cyclic group:Z5.
exponent of a group 60 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 $\operatorname{lcm} \{ 12, 5 \}$.
minimum size of generating set 2 groups with same order and minimum size of generating set | groups with same minimum size of generating set minimum size of generating set of direct product of groups of coprime order equals maximum of minimum size of generating set of each factor: the minimum size of generating set is $\max \{ 2,1 \} = 2$.
derived length 3 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 $\max \{ 3, 1 \} = 3$.

GAP implementation

Group ID

This finite group has order 120 and has ID 37 among the groups of order 120 in GAP's SmallGroup library. For context, there are 47 groups of order 120. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(120,37)

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

gap> G := SmallGroup(120,37);

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

IdGroup(G) = [120,37]

or just do:

IdGroup(G)

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