Linear OA(3²⁴⁶, 494, F₃, 72) (dual of [494, 248, 73]-code), using 1 times truncation based on linear OA(3²⁴⁷, 495, F₃, 73) (dual of [495, 248, 74]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁷, 99, F₈₁, 36) (dual of [99, 62, 37]-code), using
  - discarding factors / shortening the dual code based on linear OA(81³⁷, 100, F₈₁, 36) (dual of [100, 63, 37]-code), using
    - extended algebraic-geometric code AG_e(F,63P) [i] based on function field F/F₈₁ with g(F) = 1 and N(F) ≥ 100, using
      - a function field by SÃ©mirat [i]
2. linear OA(3¹, 5, F₃, 1) (dual of [5, 4, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
