If you've found such a set with $n$ elements, then you can find one with $n+1$ elements as follows: Take the lcm of your $n$ elements and add it to each of the $n$ elements; finally take as the $n+1$ element this lcm. E.g. start with $6$, $8$, $9$, $12$ -- their lcm is $72$, and now form $72$, $78$, $80$, $81$, $84$. | |
