• Numerator of (1+1/n)^k - (1+k/n), 2<=k<=n, triangle read by rows.at n=25A099613
• 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=50A121745
