Appears in sequences

• A doubly-fractal sequence. Erase the first (leftmost) digit of every integer: what is left is the sequence itself. The erased digits, one by one, form also the sequence itself.at n=42A127274
• Number of zero-sum -n..n arrays of 5 elements with first and second differences also in -n..n.at n=13A201876
• Number of 5-bead necklaces labeled with numbers -n..n not allowing reversal, with sum zero.at n=11A208599
• Expansion of (1 - 2*x - sqrt(1-4*x))/(4*x^2 + sqrt(1-4*x)*(3*x+1) - 5*x + 1).at n=10A242781
• Guttmann-Torrie series coefficients c_{2n}^{21} for square lattice rotated by Pi/4, with wedge angle Pi/2.at n=7A259800
• a(n) = A306302(n)/2.at n=27A331756
