| Aug 25, 2023 at 13:53 | comment | added | Peter | @DmitryKamenetsky Sure! I might have made this puzzle a little too difficult - not because it's clever but because it's not good; it sort of requires an intuitive leap, which should be avoided. But I didn't want to delete it either, since at least a couple of people have worked very well to come closer to a solution. | |

| Aug 25, 2023 at 13:04 | comment | added | matt_rule | I decided to pick an interesting number and investigate its multiples. I chose 200. For n < 14, the presence of 200*n in the list depends on whether n is a power of 2. This pattern first breaks on n=14, 17 and 19. If we restrict n to primes, the first values of n for which the multiple is not in the list are 2, 17 and 19. I don't know what to do with this information. | |

| Aug 22, 2023 at 8:15 | comment | added | Novarg | just to be sure: 84, 96 and 108 are the first(and smallest) numbers in the sequence, right? | |

| Aug 21, 2023 at 18:45 | comment | added | msh210 | Does "as far as I know" mean that you merely suspect (but do not know for certain) that there are infinitely many integers with the property? | |
