| Mar 21 at 14:36 | comment | added | Dmitry Kamenetsky | @BernardoRecamánSantos I have updated my answer. I believe there are infinitely many quadruples of consecutive Melissa numbers :) | |
| Mar 20 at 19:25 | comment | added | Dmitry Kamenetsky | @Servaes great example, thank you! | |
| Mar 20 at 18:37 | comment | added | user88375 | @DmitryKamenetsky The Melissa number $16384$ can only be done with exactly $14$ factors. | |
| Mar 20 at 13:23 | comment | added | Dmitry Kamenetsky | Is there a Melissa number that requires 4 or more factors to be constructed? | |

| Mar 20 at 6:15 | comment | added | Dmitry Kamenetsky | Great puzzle! I've spent way too much time on this without making much progress... | |
| Mar 18 at 7:12 | comment | added | geometrian | +1 because I had to make the score a Melissa number . . . | |
| Mar 17 at 2:07 | comment | added | Bernardo Recamán Santos | @GregMartin It also took me a while to realize that there are infinitely many pairs of consecutive numbers both of which are Melissa's numbers: (9,10), (99 x 100), (999, 1000), etc. Are there infinitely many triples? Don't know! Pity 101, 1001, 10001... is often prime. | |
| Mar 16 at 19:40 | comment | added | Greg Martin | Side note: it took me a little bit to determine that there were infinitely many Melissa's numbers���note the pattern $12=3\times4$, $102=3\times34$, $1002=3\times334$, $10002=3\times3334$.... | |

| Mar 13 at 16:40 | comment | added | Bernardo Recamán Santos | @CrSb0001 70 is a one of Melissa's Numbers! | |
| Mar 13 at 16:37 | comment | added | CrSb0001 | I'm currently working on finding the longest sequence of Melissa's numbers for numbers up to 100, and have a question for 70: Can I write it as 70=2*35, or do I have to write it as 70=2*7*5 and therefore 70 is not a Melissa number? | |
