• Number of 5-line partitions of n.at n=18A001452
• Coefficients of iterated exponentials.at n=4A001765
• a(n) = ceiling(10000*log(n)).at n=8A004245
• Starting positions of strings of three 3's in the decimal expansion of Pi.at n=9A083610
• a(1)=1. For n >= 2, each a(n) = the decimal equivalent of either a(k)U0Ua(k) or a(k)U1Ua(k), where U denotes concatenation of the binary representations of the arguments, and where k is some positive integer < n. The numbers are arranged in numerical order.at n=8A165784
