It's incredibly fascinating how very simple constructs like primes have such complexity to them. It's very easy for a 14 year old to formulate questions relating to primes that noone can answer.

Noone is a pretty smart guy. But there are questions that no one, not even he, can answer.

Noone is smart, but Anon is pithy. Anon came up with a ton of choice quotes and sayings, I wonder if he was a contemporary of Aesop?

what I find interesting is the amount of computing power that it takes to calculate.

Edit: As an after thought, there are recordings of million digit prime numbers: http://www.primegrid.com/download/SR5-180062.pdf

Are there chains of Sophie Germain primes?

e.g.,

    p is prime
    2p + 1 is prime
    2(2p + 1) + 1 is prime...

Wikipedia says these are called Cunningham chains: https://en.wikipedia.org/wiki/Cunningham_chain

There are no infinite chains, but there are conjectured to be inifinitely many finite chains of every possible length.

this is a great example of the title change rule making a title worse

i think taglines/subtitles/subject sentences should be eligible for titles too
