Denominators of lower primes-only best approximates (POBAs) to e; see Comments. A265815

There appear to be at least n primes in the range (x-2·sqrt(x), x] for all x >= a(n). A189027

Number of compositions of 2n into n Fibonacci parts. A341072

Primes of the form 8k+1 generated recursively. Initial prime is 17. General term is a(n)=Min {p is prime; p divides (2Q)⁴ + 1}, where Q is the product of previous terms in the sequence. A125039

Primes of the form (p² - p·q + q²)/3, where p and q are consecutive primes. A342706

Numbers k such that the continued fraction for sqrt(k) has period 69. A20408

a(1) = 2, a(2) = 3; for n>2, a(n) = least prime such that a(n-2) is the largest prime factor of a(n)+a(n-1). A126607
