OEIS Sequences

Triangular array: the fusion of (x+1)ⁿ and (x+2)ⁿ; see Comments for the definition of fusion. A193722

Number T(n,k) of simple labeled graphs on n nodes with exactly k connected components that are trees or cycles; triangle T(n,k), n>=0, 0<=k<=n, read by rows. A215861

T(n,k)=Number of nXk 0..1 arrays with row sums equal and column sums unequal to adjacent columns. A202742

a(n) = n*(5·n-3). A135706

T(n,k) = Number of n X k nonnegative integer arrays with upper left 0 and lower right n+k-5 and value increasing by 0 or 1 with every step right or down. A252976

Numbers k such that numerator of ∑_i=1..k 1/(prime(i)-1) is prime. A92063

Mirror of the fusion triangle A193722. A193723

E.g.f. A(x,k) satisfies: sin(A(x,k)) = k·sin(x). A291560

a(n) = n·A033885(A003961(n)), where A033885(n) = 3·n-σ(n), and A003961 is fully multiplicative with a(p) = nextprime(p). A388977

a(n) = ∑_{k + l·m <= n} (k + l·m), with 0 <= k,l,m <= n. A106846
