Linear OOA(3²⁴⁸, 63, F₃, 4, 195) (dual of [(63, 4), 4, 196]-NRT-code), using OOA 2-folding based on linear OOA(3²⁴⁸, 126, F₃, 2, 195) (dual of [(126, 2), 4, 196]-NRT-code), using

strength reduction [i] based on linear OOA(3²⁴⁸, 126, F₃, 2, 196) (dual of [(126, 2), 4, 197]-NRT-code), using
- juxtaposition [i] based on
  1. linear OOA(3⁸, 6, F₃, 2, 7) (dual of [(6, 2), 4, 8]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(3⁸, 7, F₃, 2, 7) (dual of [(7, 2), 6, 8]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,6P) [i] based on function field F/F₃ with g(F) = 1 and N(F) ≥ 7, using
        an explicitly constructive algebraic function field [i]
  2. linear OOA(3²³⁶, 120, F₃, 2, 188) (dual of [(120, 2), 4, 189]-NRT-code), using
    - concatenation of two NRT-codes [i] based on
      1. linear OA(9²⁸, 30, F₉, 26) (dual of [30, 2, 27]-code), using
        repeating each code word 3 times [i] based on linear OA(9⁸, 10, F₉, 8) (dual of [10, 2, 9]-code or 10-arc in PG(7,9)), using
        extended Reedâ€“Solomon code RS_e(2,9) [i]
        Simplex code S(2,9) [i]
      2. linear OOA(3⁶, 4, F₃, 2, 6) (dual of [(4, 2), 2, 7]-NRT-code), using
