Linear OA(2¹⁴⁹, 181, F₂, 56) (dual of [181, 32, 57]-code), using 3 times truncation based on linear OA(2¹⁵², 184, F₂, 59) (dual of [184, 32, 60]-code), using

concatenation of two codes [i] based on
1. linear OA(16¹⁵, 23, F₁₆, 14) (dual of [23, 8, 15]-code), using
  - discarding factors / shortening the dual code based on linear OA(16¹⁵, 24, F₁₆, 14) (dual of [24, 9, 15]-code), using
    - extended algebraic-geometric code AG_e(F,9P) [i] based on function field F/F₁₆ with g(F) = 1 and N(F) ≥ 24, 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
