• Number of rooted trees with n nodes and 10 leaves.at n=6A055285
• Triangle read by rows: T(n,k) is the number of deco polyominoes of height n and having k columns ending at an even level (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=41A121698
• Decimal representation of the diagonal from the corner to the origin of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 310", based on the 5-celled von Neumann neighborhood.at n=30A287603
• a(n) = n^4 - 3*n^3 + 9*n^2 - 7*n + 5 (n>=1).at n=15A304162
• a(n) is the least nonnegative number whose digits do not appear in order (not necessarily consecutively) in the concatenation of all previous terms.at n=31A308540
• Centered square numbers which are sphenic numbers.at n=22A380882
