• Central factorial numbers: 2nd subdiagonal of A008955.at n=4A001820
• Triangle of central factorial numbers |t(2n,2n-2k)| read by rows.at n=25A008955
• Triangle read by rows: T(n,k) is the number of deco polyominoes of height n and having k columns of odd length (0<=k<=n). A deco polyomino is a directed column-convex polyomino in which the height, measured along the diagonal, is attained only in the last column.at n=62A121745
• Triangle read by rows: matrix inverse of the central factorial numbers T(2*n, 2*k) (A036969).at n=23A204579
• Irregular triangle read by rows: T(n,k) is the number of binary pattern classes in the (7,n)-rectangular grid with k '1's and (7n-k) '0's: two patterns are in same class if one of them can be obtained by a reflection or 180-degree rotation of the other.at n=53A228166
• Triangle read by rows, Stirling cycle numbers of order 2, T(n, n) = 1, T(n, k) = 0 if k < 0 or k > n, otherwise T(n, k) = T(n-1, k-1) + (n-1)^2*T(n-1, k), for 0 <= k <= n.at n=31A269944
• a(n) = Sum_{1 <= i < j < k < m <= n} (m*k*j*i)^2.at n=6A354021
