OEIS Sequences

Number of full sets of size n. A1192

Matrix inverse of triangle A137153(n,k) = C(2^k+n-k-1, n-k), read by rows. A137156

a(0) = 0, and for n > 0, (a(n)) gives the indices n for which d(n) > d(k) for k < n, where d is the difference sequence of (cos k + sin k). A299639

a(1) = 5 and then the smallest prime that is obtained by placing digits on both sides of the previous term. Or smallest prime that encompasses a(n-1). A75598

G.f.: 1/(1-x) = (1-x·y) * ∑_k>=0 ∑_n>=k T(n,k)*xⁿ*y^k/(1+x)^{2ⁿ-2^k}. A172400
