Sep 1, 2018 at 16:53 | comment | added | Jeremy Rickard | @FilippoAlbertoEdoardo That remark only says it’s a subgroup of a group of order $p^2$, I think. The comments following Prop. 5.1 say it’s trivial (I think). | |

Sep 1, 2018 at 14:51 | comment | added | Filippo Alberto Edoardo | If you take $G$ with a normal cyclic subgroup of order $p^2$ and quotient cyclic of order $p$, I wuold say that Lewis' paper shows that $H^3(G,\mathbb{Z})$ has order $p^2$: see Remark 2.2 (2) on page 504. Am I wrong? | |
