In the category of groups the centralizer in a group G of a subset H can be redefined as: C G ⁢ ( H ) = { g ∈ G : g - 1 ⁢ h ⁢ g = h , for all ⁢ h ∈ H } . If one regards conjugation as a group action h g := g - 1 ⁢ h ⁢ g then it follows that the centralizer is the same as the pointwise stabilizer in G of H , where the action is of G on itself by conjugation.

If we avail ourselves of the unit circle on a complex plane (even higher dimension is possible ), which they introduce, we can easily solve the problem using the polar form of the number: 1 = 1 ∠ 0° = 1 ∠ 360°. 1 = 1 ∠ 120° ⋅ 1 ∠ 120° ⋅ 1 ∠ 120° = 1 ∠ 360°. So x = 1 ∠ 120° = -1/2 + (√3/2) i results in.

Given an element \(g \in G\), the “centralizer” of \(g\) is the set \(C(g) = \{h \in G \mid hgh^{-1} = g\}\), which is a subgroup of \(G\). A theorem tells us that the size of each conjugacy class is the order of the group divided by the order of the centralizer of an element of the class.
