Linear OOA(4²⁵², 128, F₄, 2, 199) (dual of [(128, 2), 4, 200]-NRT-code), using juxtaposition based on

linear OOA(4¹², 8, F₄, 2, 11) (dual of [(8, 2), 4, 12]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(4¹², 9, F₄, 2, 11) (dual of [(9, 2), 6, 12]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,6P) [i] based on function field F/F₄ with g(F) = 1 and N(F) ≥ 9, using
    - the Hermitian function field over F₄ [i]
linear OOA(4²³⁶, 120, F₄, 2, 187) (dual of [(120, 2), 4, 188]-NRT-code), using
- juxtaposition [i] based on
  1. linear OOA(4¹², 8, F₄, 2, 11) (dual of [(8, 2), 4, 12]-NRT-code) (see above)
  2. linear OOA(4²²⁰, 112, F₄, 2, 175) (dual of [(112, 2), 4, 176]-NRT-code), using
    - repeating each code word 8 times [i] based on linear OOA(4²⁴, 14, F₄, 2, 21) (dual of [(14, 2), 4, 22]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,6P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, using
        an explicitly constructive algebraic function field [i]
