OEIS Sequences

Number of unlabeled trivalent 3-connected bipartite planar graphs with 2n nodes. A7083

a(n) = (-4·n³ + 27·n² - 20·n + 3)/3. A161711

This table shows the coefficients of sum formulas of n-th Fibonacci numbers (A000045). The k-th row (k>=1) contains T(i,k) for i=1 to k, where k=[2·n+1+(-1)^n-1]/4 and T(i,k) satisfies F(n)= ∑_i=1..k T(i,k) * n^k-i/(k-1)!. A99731

T(n,k)=Number of nXk 0..2 arrays with exactly floor(nXk/2) elements equal to at least one king-move neighbor, with new values introduced in row major 0..2 order. A223033

T(n,k)=Number of nXk 0..2 arrays with no more than floor(nXk/2) elements equal to at least one king-move neighbor, with new values introduced in row major 0..2 order. A223473

Array read by antidiagonals: T(n,k) = n! * [xⁿ] exp(2·x + (k/2)*x²), n >= 0, k >= 0. A376826

Triangle read by rows: T(n,k) is the number of subpermutations of an n-set whose orbits are each of size at most k. A261763

Numbers n such that Q(sqrt(n)) has class number 9. A218041

Number of permutations σ such that |σ(i+1)-σ(i)| >= 3 for 1 <= i <= n - 1 and |σ(i+2)-σ(i)| >= 3 for 1 <= i <= n - 2. A279214

Expansion of e.g.f. exp(2·x + 3·x²/2). A202830
