• Least k such that first k terms of A022300 contain n more 2's than 1's.at n=34A025515
• Row sums of triangular matrix A102086, which shifts upward to exclude the main diagonal under matrix square.at n=6A102088
• a(0) = 0, a(1) = 1; for n >= 2, a(n) = a(n-1) + a(n-2) - (n-1) if that number is positive and not already in the sequence, otherwise a(n) = a(n-1) + a(n-2) + (n-1).at n=25A117824
