WebbIn abstract algebra, the center of a group, G, is the set of elements that commute with every element of G.It is denoted Z(G), from German Zentrum, meaning center.In set-builder notation, . Z(G) = {z ∈ G ∀g ∈ G, zg = gz}.The center is a normal subgroup, Z(G) ⊲ G.As a subgroup, it is always characteristic, but is not necessarily fully characteristic.
