OEIS Sequences

Let h(m) denote the sequence whose n-th term is ∑_k=0..n (k+1)^m*T(n,k)², where T(n,k) is the Catalan triangle A039598. This is h(7). A228333

Triangular array read by rows: a(n, k) = number of ordered factorizations of a "hook-type" number with n total prime factors and k distinct prime factors. "Hook-type" means that only one prime can have multiplicity > 1. A98348

Number of (w,x,y,z) with all terms in {1,...,n} and 2∣w-x|>=n+|y-z|. A212688

a(n) = largest k such that A049820(k) <= A262509(n). A263083

Sums of 4 distinct powers of 7. A38483

Triangle read by rows: T2[n,k] = ∑_{partitions of n with k parts p(n, k; m₁, m₂, m₃, ..., m_n)} c(n; m₁, m₂, ..., m_n) * x₁^m_1·x₂^m_2 * ... xⁿ*m_n, where x_i = i-th prime. A145520
