• Triangle read by rows in which the n-th row contains n distinct numbers whose sum is n^n. The numbers are terms of an arithmetic progression with a common difference 1 or 2 respectively accordingly as n is odd or even.at n=29A080524
• Partial sums of A162255.at n=36A164053
• a(n) = 2^n - 5.at n=21A168616
• Decimal representation of the n-th iteration of the "Rule 245" elementary cellular automaton starting with a single ON (black) cell.at n=10A267924
• 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 613", based on the 5-celled von Neumann neighborhood.at n=20A289935
• Lexicographically earliest sequence of distinct positive integers with no finite subset summing to a power of 2.at n=32A353889
