| Sep 26, 2013 at 22:01 | comment | added | Steve D | The revised question is perfectly suitable for math.SE, despite what anyone else here has said. | |
| Sep 26, 2013 at 18:24 | comment | added | Derek Holt | While Mark Sapir may have been a little rude, the fact remains that this question is not suitable for MO (it is suitable for MSE), and continuing to discuss it, attempting to improve it, etc, is just encouraging the abuse of this site. If the overall level of questions on MO keeps going down, then the experts who contribute to the discussions will start abandoning the site. | |
| Sep 26, 2013 at 17:04 | comment | added | Stefan Kohl♦ | @MichaelZieve: O.k., so this leaves only the third part (on groups whose order has only 2 distinct prime divisors). | |
| Sep 26, 2013 at 16:58 | comment | added | Michael Zieve | @StefanKohl: the smallest counterexample is $AGL(1,16)$ of order $240$. | |
| Sep 26, 2013 at 16:56 | comment | added | Alireza Abdollahi | I do not think the problem is a homework question as I have not seen it in any famous undergraduate algebra textbook that I am familiar with. | |
| Sep 26, 2013 at 16:22 | comment | added | Stefan Kohl♦ | @MarkSapir: While I agree with you that homework questions are off-topic on MO and should be removed, I think your tone is unnecessarily rude. Also, we don't know whether the question is actually the OP's homework. I have therefore chosen to try to improve the question. | |

Tried to improve the question.

| Sep 26, 2013 at 8:47 | comment | added | Tobias Kildetoft | @DerekHolt I found one before writing the first comment. It took me a few tries to find it (actually, 2 tries), but it might not be the simplest one. | |

Not suitable for this site | |
| Sep 26, 2013 at 7:46 | comment | added | Derek Holt | OK you two, how quickly can you think of a counterexample!!!! | |
| Sep 26, 2013 at 7:41 | comment | added | Tobias Kildetoft | @MarkSapir Sure, but I would still prefer to get those questions on MSE (where they are closer to being on topic) than being noise here. On the other hand, getting asked here at least means they won't get a full solution handed to them (or at least it is very unlikely). | |
| Sep 26, 2013 at 7:38 | comment | added | user6976 | @TobiasKildetoft: This is much simpler. The OP got this problem as a homework in his/her algebra class. He/she decided to post it here instead of doing the problem on his/her own. Since we do not know OP's home University and the name of the instructor, we cannot send a formal complain. So the OP is safe. | |
| Sep 26, 2013 at 6:52 | comment | added | Tobias Kildetoft | This site is meant for questions about research level mathematics, while math.stackexchange.com welcomes mathematical questions at all levels. We have recently been getting a lot of questions that are off-topic here but would have been on-topic at MSE. Could you tell us a bit about what made you select this site to post your question on, as that might help us determine how better to make sure people find the correct site in the first attempt? | |
