OEIS Sequences

Expansion of A(x) = [ ∑_n>=0 2^n*(n-1/2) * (1 + 2^2·n+1)/3·x^n*(n+1/2) ]^1/3. A370016

Triangular array T(n, k) read by rows: polynomials for the series expansion of the iterated function F^t(x) = ∑_n>=0 (1/x)^2·n-1*P_n(t)/n! with F¹(x) = (x + sqrt(x² + 4))/2 and F²(x) = F¹(F¹(x)). Row n of the triangle give the coefficients of the polynomial P_n(t). A390822

Number of primes less than 10ⁿ with initial digit 1. A73517

T(n,k)=Number of (n+1)X(k+1) 0..2 arrays with nondecreasing x(i,j)-x(i,j-1) in the i direction and nondecreasing x(i,j)+x(i-1,j) in the j direction. A250755

Number of odd p-trees of weight n (all proper terminal subtrees have odd weight). A300436

Triangle read by rows: T(n, k) is the number of ways to select k disjoint point triples from an n X n X n triangular point grid, each point triple forming a 2 X 2 X 2 triangle. A289222

Number of ways to select 4 disjoint point triples from an n X n X n triangular point grid, each point triple forming a 2 X 2 X 2 triangle. A289225

Number of 2-element intersecting families whose union is an n-element set. A53152

Pairs of deficient numbers having the same value of σ(k)/k in the order that they are found. A211680

Numbers k such that gcd(k, reverse(k)) = 27 = 3³, where reverse(x) = A004086(x). A72016
