OEIS Sequences

Triangular array generated by its row sums: T(n,0)=1 for n >= 1, T(n,1)=r(n-1), T(n,k)=T(n,k-1)+r(n-k) for k=2,3,...,n, n >= 2, r(h)=sum of the numbers in row h of T. A54115

Triangle read by rows: T(n,k) is the number of deco polyominoes of height n with k cells in the first column. (A deco polyomino is a directed column-convex polyomino in which the height, measured along the diagonal, is attained only in the last column). A100822

Triangle read by rows, T(n,k) = ∑_j=k..n j!, 0 <= k <= n. A143122

Array read by antidiagonals: T(m,n) = Sum( n <= i <= m+n-1 ) i!. A211370

Number of 4-element subsets that can be chosen from {1,2,...,4·n} having element sum 8·n+2. A204468

Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 86. A31764

Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k blocks of length 2 (0 <= k <= floor(n/2)). A block of a permutation is a maximal sequence of consecutive integers which appear in consecutive positions. For example, the permutation 5412367 has 4 blocks: 5, 4, 123, and 67; one of them is of length 2. A184183

T(n,n-2), array T as in A054115. A54117

Least number m such that A323835(m) = n. A306304

First denominator and then numerator of elements to right of central elements of 1/2-Pascal triangle (by row), excluding 2's. A46230
