• When squared gives number composed just of the digits 1, 2, 3, 4.at n=39A061677
• Triangle read by rows: T(n,k) is the number of deco polyominoes of height n and vertical height (i.e., number of rows) k (1 <= 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=39A121692
• Number of nX4 0..1 arrays with every element equal to 1, 3, 4, 5, 6, 7 or 8 king-move adjacent elements, with upper left element zero.at n=6A300142
• Number of nX7 0..1 arrays with every element equal to 1, 3, 4, 5, 6, 7 or 8 king-move adjacent elements, with upper left element zero.at n=3A300145
• T(n,k)=Number of nXk 0..1 arrays with every element equal to 1, 3, 4, 5, 6, 7 or 8 king-move adjacent elements, with upper left element zero.at n=48A300146
• T(n,k)=Number of nXk 0..1 arrays with every element equal to 1, 3, 4, 5, 6, 7 or 8 king-move adjacent elements, with upper left element zero.at n=51A300146
• G.f. A(x) satisfies: A(x) = x + x^2 + x^3 * (1 + A(A(x))).at n=14A308030
• a(n) = Motzkin(n) - 2^(n - 1 + 0^n) = A001006(n) - A011782(n).at n=13A377659
