discarding factors / shortening the dual code based on linear OOA(2²³⁸, 235, F₂, 2, 63) (dual of [(235, 2), 232, 64]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(16³⁶, 47, F₁₆, 2, 31) (dual of [(47, 2), 58, 32]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(16³⁶, 49, F₁₆, 2, 31) (dual of [(49, 2), 62, 32]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,66P) [i] based on function field F/F₁₆ with g(F) = 5 and N(F) ≥ 49, using
        a function field by SÃ©mirat [i]
