a(0)=-1, a(1)=-1, a(n)=-3·a(n-1)-a(n-2) for n>1. A98149

Expansion of (1 - x)*(1 + x)²*(1 + x²)*(1 - x² + 2·x³ + x⁴) / ((1 - x² - x⁴)*(1 + x² + 2·x⁴ - x⁶ + x⁸)). A107363

Lucas numbers beginning at 2: L(n) = L(n-1) + L(n-2), L(0) = 2, L(1) = 1. A32

Lucas numbers (beginning with 1): L(n) = L(n-1) + L(n-2) with L(1) = 1, L(2) = 3. A204
