OEIS Sequences

Numbers k such that the Woodall number k·2^k - 1 is prime. A2234

a(n) = s(1)*t(n) + s(2)*t(n-1) + ... + s(k)*t(n+1-k), where k = floor((n+1)/2), s = A023531, t = (Fibonacci numbers). A24318

Consider the base-9 Kaprekar map n->K(n) defined in A165110. Sequence gives numbers belonging to cycles, including fixed points. A165115

Numbers whose divisors can be partitioned in exactly one way into two disjoint sets with the same sum. A83209

a(n) = s(1)*t(n) + s(2)*t(n-1) + ... + s(k)*t(n+1-k), where k = floor((n+1)/2), s = A023531, t = (F(2), F(3), ...). A24322
