| Apr 25, 2020 at 8:23 | comment | added | YCor | Since it's not mentioned: for $p\ge 5$ there is (Malcev-Lazard) an equivalence of category between groups of order $p^4$ and Lie algebras of order $p^4$ over $\mathbf{Z}/p^4\mathbf{Z}$. So in a certain sense the classification is uniform for $p\ge 5$ (uniform doesn't mean the number of types depends on $p$ as it can involve parameters in $\mathbf{Z}/p\mathbf{Z}$, but the description is uniform). So the automorphism groups should be described in a uniform way too. | |

Fixed a typo in the title.
