FORMULA

From Chai Wah Wu, Sep 02 2020: (Start)

a(n) = a(n-6) - a(n-12) + a(n-18) for n > 17.

G.f.: -x*(x^16 + 16*x^15 + 9*x^14 + 16*x^13 + 25*x^12 + 24*x^8 + 25*x^4 + 16*x^3 + 9*x^2 + 16*x + 1)/(x^18 - x^12 + x^6 - 1). (End)

Period 24: repeat [0, 1, 16, 9, 16, 25, 0, 1, 16, 33, 16, 25, 0, 25, 16, 33, 16, 1, 0, 25, 16, 9, 16, 1]. - Alois P. Heinz, Sep 02 2020
