discarding factors / shortening the dual code based on linear OA(3²²³, 495, F₃, 61) (dual of [495, 272, 62]-code), using
- concatenation of two codes [i] based on
  1. linear OA(81³¹, 99, F₈₁, 30) (dual of [99, 68, 31]-code), using
    - discarding factors / shortening the dual code based on linear OA(81³¹, 100, F₈₁, 30) (dual of [100, 69, 31]-code), using
      - extended algebraic-geometric code AG_e(F,69P) [i] based on function field F/F₈₁ with g(F) = 1 and N(F) ≥ 100, using
