Which group of order is abelian?

Could you please elaborate on which group of order you are referring to when asking if it is abelian? In mathematics, a group is considered abelian if its operation is commutative, meaning that for any two elements a and b in the group, the result of the operation a applied to b is the same as the result of b applied to a. This property is not inherent to all groups, so it's important to specify the group in question to determine if it is indeed abelian.
