==Definition==
This [[group]] is the [[semidirect product]] <math>(Z_2 \times Z_2) \rtimes Z_9</math>. Explicitly, it is given by:
<math>\langle a,b,x \mid a^2 = b^2 = x^9 = e, xax^{-1} = b, xbx^{-1} = ab \rangle</math>
where <math>e</math> denotes the identity element.

Definition

This group is the semidirect product . Explicitly, it is given by:

where denotes the identity element.

Arithmetic functions

Want to compare and contrast arithmetic function values with other groups of the same order? Check out groups of order 36#Arithmetic functions

Function Value Similar groups Explanation for function value
order (number of elements, equivalently, cardinality or size of underlying set) 36 groups with same order
exponent of a group 18 groups with same order and exponent of a group | groups with same exponent of a group
minimum size of generating set 3 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 36 and has ID 1 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(36,1)

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

gap> G := SmallGroup(36,1);

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

IdGroup(G) = [36,1]

or just do:

IdGroup(G)

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