In S3, the ,centralizer, of (1,2,3) is equal to h(1,2,3)i, since it is easy to check that (1,2) does not belong to the ,centralizer,, and by Lagrange’s theorem a proper subgroup ,of a group, with 6 elements can have at most 3 elements. To find the ,centralizer, of (1,2,3) in S4 we have to work a bit harder. Let a = (1,2,3).

center/centralizer of a group? abelian? | Yahoo Answers

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.
