a(n) = ∑_k=1..n floor((n/k)ⁿ). A347416

G.f. satisfies A(x) = exp( ∑_k>=1 (2 * (-1)^k + A(x^k)) * x^k/k ). A363565

Expansion of ∏_k>=2 (1 - x^k)^k. A298599

Numbers that are congruent to {2, 4} mod 8. A47463

a(n) is the number of distinct primes produced by starting with the n-th prime p and repeatedly looking at all the prime factors of 2p-1, and then performing the same process (double, subtract 1, find all prime factors) with those primes; a(n) = -1 if this produces infinitely many primes. A298904
