Linear OOA(2²⁴⁰, 68, F₂, 6, 78) (dual of [(68, 6), 168, 79]-NRT-code), using OOA 2-folding based on linear OOA(2²⁴⁰, 136, F₂, 3, 78) (dual of [(136, 3), 168, 79]-NRT-code), using

strength reduction [i] based on linear OOA(2²⁴⁰, 136, F₂, 3, 79) (dual of [(136, 3), 168, 80]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(8⁴⁶, 34, F₈, 3, 39) (dual of [(34, 3), 56, 40]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,62P) [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]
