Expansion of (2/π)*elliptic_E(k) in powers of q. A194094

a(n) is the smallest error in trying to solve n⁵ = x⁵ + y⁵: for each n from 2 on, find positive integers·and y, x <= y < n such that |n⁵ - x⁵ - y⁵| is minimal and let a(n) = n⁵ - x⁵ - y⁵. In case of a tie, choose the solution with smallest y. A369855
