Is d4 not abelian?

Excuse me, could you please clarify for me if the group denoted as d4 is indeed not abelian? I understand that in mathematics, an abelian group is one in which the group operation is commutative, meaning that the order of the elements being operated on does not affect the result. So, in the context of d4, which I assume refers to the dihedral group of order 4, is it the case that the multiplication of its elements does not satisfy this commutative property? I'm curious to know if there's a specific reason why d4 is not considered an abelian group.
