Definition

This group is the semidirect product $(Z_{2}\times Z_{2})\rtimes Z_{9}$. Explicitly, it is given by:

$\langle a,b,x\mid a^{2}=b^{2}=x^{9}=e,ab=ba,xax^{-1}=b,xbx^{-1}=ab\rangle$

where $e$ denotes the identity element.

GAP implementation

Group ID

This finite group has order 36 and has ID 3 among the groups of order 36 in GAP's SmallGroup library. For context, there are groups of order 36. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(36,3)

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

gap> G := SmallGroup(36,3);

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

IdGroup(G) = [36,3]

or just do:

IdGroup(G)

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