| May 14 at 11:49 | comment | added | JP McCarthy | As an aside, regarding the other element of the paper, a remark, I believe if a finite group $G$ is the classical version of a quantum permutation group $\mathbb{G}$, then inner automorphisms of $G$ extend to automorphisms of $\mathbb{G}$. | |
| May 9 at 4:39 | comment | added | Brauer Suzuki | @SamHopkins You can see under his answer that I asked YCor already in 2021 about a paper. I never got a reply. | |
| May 8 at 19:42 | comment | added | Sam Hopkins | I'll split the difference between LSpice and Alex M. and say that while the article gives appropriate attribution, it still would have been best to reach out to YCor before posting to the arXiv. | |
| May 8 at 18:55 | comment | added | Alex M. | @LSpice: Proper credit has been given, though, together with a link to the YCor's MO answer. Furthermore, the proof published on arXiv diverges from the one on MO significantly, by replacing the Lie group-theoretical arguments with purely group-theoretical ones. Therefore, it is not a reposting of YCor's proof, but a modification of it. | |

| May 8 at 17:45 | comment | added | LSpice | Although it's not my place to argue, I find myself uncomfortable with the idea of taking someone else's MO answer and posting a version of it on the arXiv. But perhaps you communicated separately with @YCor before doing so. | |
