| Oct 10, 2023 at 11:03 | comment | added | YCor | To be explicit, the simplest example seems to be the inclusion $U(F_1)\subseteq U(F_2)$ with $F_2$ the symmetric group on 3 elements, and $F_1$ cyclic of order 2, i.e., generated by a transposition. | |

| Oct 10, 2023 at 9:10 | comment | added | YCor | Your definition of $G$ is strange because many elements of the coset $\mathrm{Aut}(G)\smallsetminus T$ have no inversion (e.g., a translation of odd length). $G$ is just the group of elements mapping one/every vertex to even distance. | |
