Linear OOA(2²⁰⁹, 127, F₂, 3, 62) (dual of [(127, 3), 172, 63]-NRT-code), using 1 step truncation based on linear OOA(2²¹⁰, 128, F₂, 3, 63) (dual of [(128, 3), 174, 64]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8³⁸, 32, F₈, 3, 31) (dual of [(32, 3), 58, 32]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8³⁸, 34, F₈, 3, 31) (dual of [(34, 3), 64, 32]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,70P) [i] based on function field F/F₈ with g(F) = 7 and N(F) ≥ 34, using
      - a function field by SÃ©mirat [i]
2. linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 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]
