| Jun 8, 2020 at 14:25 | comment | added | Goulifet | Is it obvious that we capture all the direct similarities doing so? | |
| Jun 8, 2020 at 13:33 | comment | added | Goulifet | That's nice, using the "vector quaternions" for $\mathbb{R}^3$ and then describing the geometric transformations as exposed does the job. Thanks a lot! | |
