| Oct 13, 2023 at 15:12 | comment | added | YCor | Your assertion that $h\in H$ implies $|\langle G,h\rangle|=2|G|$ is incorrect. Indeed $\langle G,h\rangle\cap\mathrm{SO}_n$ can be larger than $G$ (pick $G=\{1\}$ to find the most trivial counterexamples). Or add the condition $\langle G,h\rangle\cap\mathrm{SO}_n=G$ in your definition of $H$. | |
