Shit. When I was reading through I suspected you were one of the remote literature researchers because this has the makings of a good literature review article I think.
Sorry. I probably should have linked happy and sexy. I was saying that the “happy” component fit well with the topic. Sexy was just an added bonus.
To summarize:
If you take a number, sum the squares of its digits to make a new number, then do the same with the next number and it eventually reaches one through that process, it is a “happy” number. “Happy prime” just refers to those prime numbers which are happy.
Demonstration: 3^2+1^2=10 and
1^2+0^2=1
a sexy prime differs from another prime by 6 (in this case; 37).
I think this would do well in Main.
Yes, it most certainly doesn’t belong here. Move it to main please author! (Whereupon Eliezer should promote it.)
1 karma point to go :)
eta: I have 19 karma at the moment.
Oh, wow. Welcome to lesswrong in that case! Best introductory post I recall seeing!

I upvoted your post to a nice round 20. It’s a much nicer number than 19 anyway.
I’m saddened that it’s no longer prime.
Upvoting to 31, which is quite a fantastic number, since it is both (aptly) a “happy” prime, as well as a “sexy” prime.
Explain?
