removed the deprecated (geometry) tag - see the tag info: https://mathoverflow.net/tags/geometry/info; if there are some other geometry-related tags which are suitable, please use some of them instead

Oct 2, 2018 at 14:16 | comment | added | M. Winter | @HenrikRüping Thank you for your comment. I hoped it would be clear from my explanation that arc-transitivity includes edge- and vertex-transitivity. Unfortunately a rhombus is not vertex-transitive. I will improve my post. | |
