The Derbyshire challenge:
… find anything interesting to say about the number 2017.
Yes, it’s a prime, the 306th. (The 2,017th prime, which I know you’re now wondering about, is 17,539. The last prime year was 2011; the next is 2027; the gaps there, average size 8, are what you’d expect, since log (2017) = 7.60936653795.)
Find something else.
