Linear OA(2¹⁸², 230, F₂, 61) (dual of [230, 48, 62]-code), using 2 times truncation based on linear OA(2¹⁸⁴, 232, F₂, 63) (dual of [232, 48, 64]-code), using

concatenation of two codes [i] based on
1. linear OA(16¹⁷, 29, F₁₆, 15) (dual of [29, 12, 16]-code), using
  - discarding factors / shortening the dual code based on linear OA(16¹⁷, 33, F₁₆, 15) (dual of [33, 16, 16]-code), using
    - extended algebraic-geometric code AG_e(F,17P) [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
