Linear OOA(2²²⁸, 137, F₂, 3, 69) (dual of [(137, 3), 183, 70]-NRT-code), using 1 times NRT-code embedding in larger space based on linear OOA(2²²⁵, 136, F₂, 3, 69) (dual of [(136, 3), 183, 70]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁴¹, 34, F₈, 3, 34) (dual of [(34, 3), 61, 35]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(3;F,67P) [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]
