Appears in sequences

• Sieve performed by successive iterations of steps where step m is: keep m terms, remove the next 2 and repeat; as m = 1,2,3,.. the remaining terms form this sequence.at n=41A112560
• Inverse binomial transform of A144472.at n=14A145593
• Number of nondecreasing integer sequences of length 6 with sum zero and sum of absolute values 2n.at n=34A158140
• T(n,k) = total area of all squares and rectangles of area 2^(k-1) after 2^n stages in the toothpick structure of A139250, n>=1, k>=1, assuming the toothpicks have length 2. Triangle read by rows.at n=29A211017
• Vinogradov's number J_{3,2}(n).at n=15A281391
• Relative of Hofstadter Q-sequence: a(n) = max(0, n+27298) for n <= 0; a(n) = a(n-a(n-1)) + a(n-a(n-2)) + a(n-a(n-3)) for n > 0.at n=7A283888
