• Decimal representation of the x-axis, from the origin to the right edge, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 331", based on the 5-celled von Neumann neighborhood.at n=19A281179
• For numbers x_n coprime to 10 there exist infinitely many binary numbers b such that gcd(b,rev(b)) = x_n and digitsum(b) = x_n. a(n) is the smallest b converted to decimal that satisfies this constraint.at n=6A348480
