OEIS Sequences

Least odd number k such that x' = k has n solutions, where x' is the arithmetic derivative (A003415) of x. A189560

a(n) = Sum from "least·such that prime(x) has n digits" to "the number of primes with n digits" of the difference between prime(k) and k. A261806

Indices where A092243 strictly changes sign. A269737

Numbers which can be decomposed as p·q + q·r + r·p (where p < q < r are distinct primes) in more ways than any smaller number. A237992

a(1) is 4. a(n) is the least semiprime q (A001358) greater than p = a(n-1), such that p/q is a new minimum. A277343

a(n) is the least number that can be written in exactly n ways as p·q + q·r + p·r where (p,q,r) is an unordered triple of distinct primes. A356457
