| May 7, 2020 at 8:43 | comment | added | Jaap Scherphuis | The site I linked used a method for generating perfect modular Golomb rulers for $n=p^k+1$, i.e. a prime power plus 1. Apart from $3$, these are never prime. | |

| May 7, 2020 at 8:41 | comment | added | Dmitry Kamenetsky | @JaapScherphuis I believe you are right about the largest n. Hence I added a third question about non-prime n. | |

| May 7, 2020 at 8:23 | comment | added | Jaap Scherphuis | From what I read on this site there probably is no largest $n$ for a perfect modular Golomb ruler. | |
| May 7, 2020 at 7:21 | comment | added | daw | I.e., two points on the circle with distance 2,3. Distance 1 can be measured by subtracting | |
| May 7, 2020 at 7:16 | comment | added | daw | How does measuring work? Can [2,3] be used to measure a distance of 1? | |
