Linear OA(2⁹⁸, 154, F₂, 30) (dual of [154, 56, 31]-code), using 1 times truncation based on linear OA(2⁹⁹, 155, F₂, 31) (dual of [155, 56, 32]-code), using

concatenation of two codes [i] based on
1. linear OA(16¹⁷, 31, F₁₆, 15) (dual of [31, 14, 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(2¹, 5, F₂, 1) (dual of [5, 4, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
