Counting Centralizers in Finite Groups

Can #Cent(G) = 4? Yes, the dihedral group on four symbols, D4, and the quater-nion group of order eight, Q, are groups with exactly four centralizers. For example, the distinct, centralizers of D4,, written as unions of right cosets of the center, are D4= Z U Z (1,2,3,4) u Z (1,2)(3,4) U Z (1,3), P=ZUZ (1,2,3,4), R =ZuZ (1,2)(3,4), S=ZuZ (1,3),

Centers and Centralizers - Graceland University

The, centralizer, of a in G, denoted C(a), is the set of elements that commutes with a. That is, C(H) in, D4, In, D4,, C(H) = {R0, R180, H, V} Prove: C(a) ≤ G Proof: Let a be an element of a group G. We will use the one-step test to show that C(a) is a subgroup. ea = ae, so e belongs to C(a). Hence C(a) is nonempty.
