A comment on Sexy prime.

They're primes which are separated by exactly six non-prime numbers. It remains an open question whether or not there are infinitely many sexy primes.

More generally, see the article on prime gaps: https://en.m.wikipedia.org/wiki/Prime_gap

That doesn't match what the article says: "prime numbers that differ from each other by six". So they're separated by five other numbers (which are not necessarily all non-primes).

Separated by five natural numbers.

separated by is 1 less than the difference, so separated by 5 composite numbers is what you meant? i mean it's just a wording issue.

Yes, that’s what I meant. Thanks for the charitable correction.

Great to see the HN tradition of downvoting for an off by one error continues strong as well...
