OEIS Sequences

Triangular array: T(n,k) counts the partitions of the set [n] into k odd sized blocks. A136630

Triangle of central factorial numbers 4^k T(2n+1, 2n+1-2k). A8958

Triangle of scaled central factorial numbers, T(n,k) = A008958(n,n-k). A160562

Central factorial numbers: 2nd subdiagonal of A008958. A2453

Exponential Riordan array (1,sin(x)). A185690

T(n,k) is the number of permutations of [n] having exactly k pairs of integers i<j in [n] such that their cycle minima have opposite sorting order; triangle T(n,k), n>=0, 0<=k<=A125811(n)-1, read by rows. A381529

Square array A(n,k), n >= 0, k >= 0, read by antidiagonals downwards, where A(n,k) = (2·n+k)!/k! * [x^2·n+k] sinh(x)^k. A381512

Triangle read by rows: T(n,k) (0 <= k <= n) is the number of Delannoy paths of length n, having k return steps to the line y = x from the line y = x+1 (i.e., E steps from the line y=x+1 to the line y = x). A110098

Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k triple descents (n>=0,0<=k<=n-3). We say that i is a triple descent of a permutation p if p(i) > p(i+1) > p(i+2) > p(i+3). A220183

a(n) = (25·n⁴-120·n³+209·n²-108·n)/6. A6529
