OEIS Sequences

Aitken's array: triangle of numbers {a(n,k), n >= 0, 0 <= k <= n} read by rows, defined by a(0,0)=1, a(n,0) = a(n-1,n-1), a(n,k) = a(n,k-1) + a(n-1,k-1). A11971

Number of one-element transitions from the partitions of n to the partitions of n+1 for labeled parts. A93694

Sum over all partitions of n of the LCM of the parts. A181844

T(n,k)=Number of nXk 0..3 arrays x(i,j) with each element horizontally, vertically or antidiagonally next to at least one element with value (x(i,j)+1) mod 4, no adjacent elements equal, and upper left element zero. A230910

a(n) = S1(n,4), where S1(n,t) = ∑_k=0..n k^t * ∑_j=0..k binomial(n,j). A89661
