Definition

This group is a semidirect product $Z_{3}\rtimes Q_{16}$. It is given by:

$\langle a,x,y\mid a^{3}=x^{8}=y^{4}=e,x^{4}=y^{2},ax=xa,yay^{-1}=a^{-1},yxy^{-1}=x^{-1}\rangle$

where $e$ denotes the identity element.

GAP implementation

Group ID

This finite group has order 48 and has ID 8 among the groups of order 48 in GAP's SmallGroup library. For context, there are groups of order 48. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(48,8)

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

gap> G := SmallGroup(48,8);

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

IdGroup(G) = [48,8]

or just do:

IdGroup(G)

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