Aside from that, it's helpful to make "in char 0" more precise, since one usually starts by working over an algebraically closed field such as $\mathbb{C}$ followed by comparisons with representations over arbitrary fields. | |

| Jul 17, 2015 at 10:27 | comment | added | Derek Holt | After reading Geoff Robinson's answer, I found the earlier post, which is mathoverflow.net/questions/191769 So perhaps this question should be regarded as a duplicate? | |

| Jul 17, 2015 at 9:20 | comment | added | Derek Holt | A sylow $2$-subgroup would have to be cyclic or generalized quaternion, which restricts the structure. I wonder if there are any interesting odd order examples. | |
| Jul 17, 2015 at 9:16 | comment | added | Jeremy Rickard | Also generalized quaternion groups. | |
| Jul 17, 2015 at 8:27 | comment | added | Derek Holt | All nontrivial cyclic groups, ${\rm SL}(2,5)$ and its subgroups. | |
