| Aug 17, 2013 at 5:39 | comment | added | S. Carnahan♦ | Basic observations: $C_G(x)/Z(G)$ is an elementary 2-group, and $C_G(x) \subset Z_2(G)$ (from the upper central series). | |
| Aug 16, 2013 at 21:55 | comment | added | Yemon Choi | Yes, but what prompted you to check this in the first place? I assume this was not just a question that occurred to you out of the blue, so why not give us some more background? | |

| Aug 16, 2013 at 21:41 | comment | added | Yemon Choi | I can't speak for others, but personally I would like to know some of the motivation behind a question before spending time thinking about it | |
| Aug 16, 2013 at 21:30 | comment | added | Nashenas | Do you have any counterexample? | |
| Aug 16, 2013 at 21:27 | comment | added | Yemon Choi | Why do you think this should be true? Why do you want it to be true, i.e. where does this question originate? | |
