OEIS Sequences

Lexicographically earliest sequence of distinct positive integers with no finite subset summing to a positive Fibonacci number. A353966

Fibonacci sequence beginning 3, 14. A22125

Variation on Ulam numbers: a(1) = 1; a(2) = 2; for n>2, a(n) is smallest (n odd) or largest (n even) new number that is the sum of two distinct earlier terms. A81025

For even n>=4, let f(n)=A066285(n/2) be the minimal difference between primes p and q whose sum is n. This sequence contains the successive maxima of f. A66286
