discarding factors / shortening the dual code based on linear OA(2²³⁷, 305, F₂, 77) (dual of [305, 68, 78]-code), using
- concatenation of two codes [i] based on
  1. linear OA(16⁴⁴, 61, F₁₆, 38) (dual of [61, 17, 39]-code), using
    - discarding factors / shortening the dual code based on linear OA(16⁴⁴, 64, F₁₆, 38) (dual of [64, 20, 39]-code), using
      - algebraic-geometric code AG(F,25P) [i] based on function field F/F₁₆ with g(F) = 6 and N(F) ≥ 65, using
        the Hermitian function field over F₁₆ [i]
  2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 2]-code), using
