Non-Abelian


A group or other algebraic object is called non-Abelian if the law of commutativity does not always hold, i.e., if the object is not Abelian. For example, the group of nonsingular matrices is non-Abelian, as can be seen by comparing

 [1 0; 0 -1][0 1; -1 0]=[0 1; 1 0]

and

 [0 1; -1 0][1 0; 0 -1]=[0 -1; -1 0].
