| Nov 15, 2019 at 7:44 | comment | added | Martin Sleziak | On Mathematics, you can find several posts which are about finding closure (or limit points) of this set. For example: Find the limit points of the set $\{ \frac{1}{n} +\frac{1}{m} \mid n , m = 1,2,3,\dots \}$ and the posts linked there. | |
