What is inverse edge?

...but edges are not equivalent to their inverses...

What means inverses in that case? Jumpow (talk) 20:19, 22 January 2019 (UTC)

Presumably it means that there is no symmetry of the graph that takes an edge to itself but swaps the two endpoints of the edge. I agree that it could be worded more clearly. —David Eppstein (talk) 21:10, 22 January 2019 (UTC)

New version

I've created and uploaded a new version of the Holt graph:

I think it's better than the current version, as it's less cluttered and easier to see which line connects what. Please let me know your opinions. And any suggestions, such as making the vertices larger/smaller, or the green greener/less green. (As I look at it now, I feel the inner star-nonagon should be rotated clockwise 10°.)

Agree that it's better than current. I would prefer either making the stars all exactly in-phase with each other or exactly out-of-phase, rather than with seemingly haphazard rotations. —David Eppstein (talk) 19:15, 27 July 2022 (UTC)

Adjusted so the outer two are in phase, the inner one in antiphase. Maproom (talk) 20:54, 27 July 2022 (UTC)

Yes, I think that looks even better. —David Eppstein (talk) 22:56, 27 July 2022 (UTC)
