Definition

This group is defined by the following presentation:

$G:=\langle a,x,y\mid x^{2}=a^{4}=y^{4}=e,xax^{-1}a^{-1}=y^{2},ay=ya,xyx^{-1}y^{-1}=a^{2}\rangle$

order (number of elements, equivalently, cardinality or size of underlying set)	32	groups with same order
prime-base logarithm of order	5	groups with same prime-base logarithm of order
max-length of a group	5		max-length of a group equals prime-base logarithm of order for group of prime power order

GAP implementation

Group ID

This finite group has order 32 and has ID 31 among the groups of order 32 in GAP's SmallGroup library. For context, there are groups of order 32. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(32,31)

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

gap> G := SmallGroup(32,31);

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

IdGroup(G) = [32,31]

or just do:

IdGroup(G)

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