Linear OOA(3¹⁹⁸, 54, F₃, 4, 140) (dual of [(54, 4), 18, 141]-NRT-code), using generalized (u,Â u+v)-construction based on

linear OOA(3⁵⁵, 18, F₃, 4, 46) (dual of [(18, 4), 17, 47]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(3⁵⁵, 19, F₃, 4, 46) (dual of [(19, 4), 21, 47]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(4;F,29P) [i] based on function field F/F₃ with g(F) = 9 and N(F) ≥ 19, using
    - an explicitly constructive algebraic function field [i]
linear OOA(3⁷¹, 18, F₃, 4, 70) (dual of [(18, 4), 1, 71]-NRT-code), using
- strength reduction [i] based on linear OOA(3⁷¹, 18, F₃, 4, 71) (dual of [(18, 4), 1, 72]-NRT-code), using
  - dual of repetition NRT-code with length 18 [i]
linear OOA(3⁷², 18, F₃, 4, 72) (dual of [(18, 4), 0, 73]-NRT-code), using
