Linear OA(2¹⁸⁵, 221, F₂, 68) (dual of [221, 36, 69]-code), using 3 times truncation based on linear OA(2¹⁸⁸, 224, F₂, 71) (dual of [224, 36, 72]-code), using

concatenation of two codes [i] based on
1. linear OA(16¹⁹, 28, F₁₆, 17) (dual of [28, 9, 18]-code), using
  - discarding factors / shortening the dual code based on linear OA(16¹⁹, 33, F₁₆, 17) (dual of [33, 14, 18]-code), using
    - extended algebraic-geometric code AG_e(F,15P) [i] based on function field F/F₁₆ with g(F) = 2 and N(F) ≥ 33, using
      - a function field by SÃ©mirat [i]
2. linear OA(2⁴, 8, F₂, 3) (dual of [8, 4, 4]-code or 8-cap in PG(3,2)), using
