Linear OOA(3¹⁸⁶, 54, F₃, 4, 108) (dual of [(54, 4), 30, 109]-NRT-code), using OOA 2-folding based on linear OOA(3¹⁸⁶, 108, F₃, 2, 108) (dual of [(108, 2), 30, 109]-NRT-code), using

strength reduction [i] based on linear OOA(3¹⁸⁶, 108, F₃, 2, 110) (dual of [(108, 2), 30, 111]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(9³⁹, 27, F₉, 2, 36) (dual of [(27, 2), 15, 37]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(9³⁹, 28, F₉, 2, 36) (dual of [(28, 2), 17, 37]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,19P) [i] based on function field F/F₉ with g(F) = 3 and N(F) ≥ 28, using
        the Hermitian function field over F₉ [i]
  2. linear OA(3², 4, F₃, 2) (dual of [4, 2, 3]-code or 4-arc in PG(1,3)), using
