| Mar 8, 2023 at 6:24 | comment | added | Iosif Pinelis | "describe all possible examples" ... Describe in what (non-tautological) terms? | |
| Mar 8, 2023 at 6:00 | comment | added | Markiian Khylynskyi | @IosifPinelis Indeed, the latter example can be generalized as $\{(a,b)\mid a>f(b)\}$ where $f$ is a monotonic function on $\mathbb{Z}$. Maybe it can be generalized yet. Maybe one can to describe all possible examples. What if $A$ is uncountable? | |
| Mar 7, 2023 at 22:46 | comment | added | Iosif Pinelis | It is still unclear what your goal here is. "Are there any other examples?" Of course, there are. For instance, such modifications of your latter example as $\{(a,b)\in\mathbb{Z}^2\mid a > b+1\}$ are also examples of $S$. As stated, your question seems impossible to answer satisfactorily. | |

| Mar 7, 2023 at 19:03 | comment | added | Iosif Pinelis | Each of the sets $\{(a,c)\mid (a,c)\in S\}$, $\{(b,c)\mid (b,c)\in S\}$, $\{(c,a)\mid (c,a)\in S\}$, $\{(c,b)\mid (c,b)\in S\}$ equals $S$. So, what is your question really about? | |
