• Triangle read by rows: T(n,k) is the number of deco polyominoes of height n and having k 1-cell columns (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=47A121554
• Minimum perimeter of n-tuples of Heronian triangles with equal perimeter and equal area.at n=8A198311
• Sum of the asymmetry degrees of all compositions of n with parts in {3,4,5,6, ...}.at n=32A276059
• Triangle read by rows: T(n, k) = n^k * Sum_{j=0..n} binomial(n - j, n - k) * Eulerian1(n, j).at n=30A372311
