Linear OA(4²⁰⁰, 218, F₄, 125) (dual of [218, 18, 126]-code), using 2 times truncation based on linear OA(4²⁰², 220, F₄, 127) (dual of [220, 18, 128]-code), using

concatenation of two codes [i] based on
1. linear OA(16³⁵, 44, F₁₆, 31) (dual of [44, 9, 32]-code), using
  - discarding factors / shortening the dual code based on linear OA(16³⁵, 45, F₁₆, 31) (dual of [45, 10, 32]-code), using
    - extended algebraic-geometric code AG_e(F,13P) [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(4³, 5, F₄, 3) (dual of [5, 2, 4]-code or 5-arc in PG(2,4) or 5-cap in PG(2,4)), using
