Appears in sequences

• Moebius transform of A000011 (starting at term 0).at n=22A054183
• Number of bracelet structures using exactly two different colored beads.at n=21A056357
• Number of numbers k which give 1 after applying exactly n iterations of the 3k+1 algorithm (if a number is even, divide it by 2; if it is odd, multiply by 3 and add 1). This total includes numbers k which also give 1 for a smaller number of iterations (i.e., for this sequence we do not assume the algorithm halts when 1 is reached).at n=45A082538
• Primes of the form 14 n^2-1.at n=16A143832
• a(n) = index of second occurrence of A161926(n) in A114381.at n=20A161927
• Starhex honeycomb numbers: a(n) = 13 + 60*n + 60*n^2.at n=28A332243
• Number of ways to tile a strip of length n with squares, dominoes and trominoes, using an equal number of dominoes and trominoes.at n=22A387599
• Prime numbersat n=5010
