Appears in sequences

• Let f(n) = exp(Pi*sqrt(n)); sequence gives numbers n such that ceiling(f(n)) - f(n) < 1/10^4.at n=12A127023
• Least positive integer k such that 1 + 1/2 + ... + 1/k > n/3.at n=34A226187
• Start with a single square; at n-th generation add a square at each expandable vertex; a(n) is the sum of all label values at n-th generation. (See comment for construction rules.)at n=13A247618
• a(n) = 2^(n - 1) - prime(n).at n=16A277801
• 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 539", based on the 5-celled von Neumann neighborhood.at n=15A289044
