OEIS Sequences

Number of integer partitions of n that are not pairwise coprime, where a singleton is not coprime unless it is (1). A335240
a(0)=1; for n >= 1, a(n) = ∑k=0..n 11k*N(n,k) where N(n,k) = (1/n)*C(n,k)*C(n,k+1) are the Narayana numbers (A001263). A82173
Future of the smallest-perizeroin komet in Kimberling's expulsion array (A035486). A38807
a(n) = N(5,n), where N(5,x) is the 5th Narayana polynomial. A90198
a(n) = number of triangles with integer sides i <= j <= k with radius of circumcircle <= n. A331229
Triangle read by rows: T(n,k) is the number of binary trees with n edges and jump-length equal to k (n >= 0, 0 <= k <= n-2). A127532
Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n-2)*b(n-1), where a(0) = 2, a(1) = 3, b(0) = 1, b(1) = 4, and (a(n)) and (b(n)) are increasing complementary sequences. A296263
Multiplicity of the zero at x=1 of the characteristic polynomial PnC. A246997
Table T(n,k), n>=0 and k>=0, read by antidiagonals: the k-th column given by the k-th Narayana polynomial. A8550
Numbers k such that the LCM of all possible sums of two digits of k (at distinct positions) is strictly greater than k. A308534
