Find the order of the centralizer of the cycle (12345) of ...

4/6/2012, · This follows because conjugating any ,element, in S5 yields another elemnt with the same cycle ,structure, (e.g. 3 cycles are only conjugated to 3 cycles, products of transpositions are only conjugated to products of transposition,etc.). Thus, the ,centralizer, of the cycle (12345) contains all the other 5-cycles in S5 and the identity.

Thus a finite group in which every ,centralizer, of a non-identity ,element, is cyclic. is itself metacyclic. More information about prime divisors would be needed to ... of the original question, that all centralizers are cyclic, illustrates that these groups have more restricted ,structure, than groups with all Sylow subgroups cyclic.

13/9/2007, · An easy counterexample is to take G a nonabelian group, and look at the ,centralizer, of the identity ,element,, which easy to show to be G. The answer to the second question is yes. If a and b are any two elements of the center, then by definition of the center a commutes with b, so ab=ba for any two a and b in the center of G.
