Number of maximal sets of partitions of n with property that all parts in all partitions in the set are distinct. A68598

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n+1-k), where k = [ (n+1)/2 ], s = (composite numbers), t = (primes). A24604

The i-th term of the generalized Fibonacci sequence [0,k,k,2k,3k,...] is given by the formula F(i) = round( k/sqrt(5) * φⁱ ) provided i >= s(k); a(n) = smallest value of k such that s(k) = n. A111917

Numbers k whose binary expansion is a substring of the binary expansion of binomial(k,2). A356537
