Spitballing here, but I suspect it's a density thing. If you are considering all prime powers up to some bound N, then the density of prime powers (edit: of size p^n with n > 1) ap…

I've never considered something like this before. I like the way you've phrased this too. I'm going to give this a shot for a few weeks.

Just speculating here, but isn't it quite possible someone wasn't intentionally sitting on it for 14 years and instead just couldn't access it? For example, if they've been sitting…
