a(n) = 1 + 3·n - 2·n². A168244

G.f. satisfies: A(x) = 1 + ∑_n>=1 (A(x)ⁿ + A(x)^-n) * x^n². A190791

a(n) is the smallest error in trying to solve n⁴ = x⁴ + y⁴. That is, for each n from 2 on, find positive integers·and y, x <= y < n such that |n⁴ - x⁴ - y⁴| is minimal and let a(n) = n⁴ - x⁴ - y⁴. A308834
