Okay, interesting, though irrelevant to my conjecture, since I didn't claim that only multiples of 9 would be "demure", merely that the multiples of 9 all were (didn't actually get around to proving this yet, btw, so still just a conjecture, unless you've proven it or seen the proof).
I fail to see why it's all fluffy and special that 18 is the only one whose demure number is 2. Maybe that's because I'm just not that into number theory, relative to other areas of math (probably mostly because I haven't done much of it). But, basically, why do I care that 18 is the only number which is demure for 2 (perhaps this will be addressed by your later post)?
