• Triangle read by rows: T(n,k) is the number of deco polyominoes of height n and having k columns of even 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=39A121748

• Number of (n+1)X(4+1) 0..5 arrays with every 2X2 subblock having the sum of the absolute values of all six edge and diagonal differences equal to 15.at n=2A234204
• T(n,k)=Number of (n+1)X(k+1) 0..5 arrays with every 2X2 subblock having the sum of the absolute values of all six edge and diagonal differences equal to 15.at n=17A234208
