Small fragment of n²+n+1 vs n²-n+41 ~50% primes in n²+n+1 vs 100% primes in n²-n+41 It's interesting that both of them end with 1,3,7,3,1 pattern.pic.twitter.com/EOUvR5EksI

Since all primes > 10 end with 1,3,7 or 9, it's not that surprising. :)
EN SERIO?
So about 7Pi% then.
the long primes will rescue the universe
Yes this is curious: (i) this is a famous polynomial so you didn't cherry pick; (ii) 99% of these primes exceed 100Million with prime density less than 1/log(10Million) = 14.3% (by Prime Number Theorem); so (iii) Law of Large Numbers --> very unlikely to be due to chance random.
It’s more interesting if you also state that random sampling from the set of integers less than a million, the chances of selecting a Prime are around 7.85%
Yeah I see, it's basically like this: a[n] - a[n-1] = 2*(n-1)
