Linear OOA(3¹⁹⁹, 103, F₃, 2, 130) (dual of [(103, 2), 7, 131]-NRT-code), using juxtaposition based on

linear OOA(3³¹, 19, F₃, 2, 22) (dual of [(19, 2), 7, 23]-NRT-code), using
- extended algebraic-geometric NRT-code AG_e(2;F,15P) [i] based on function field F/F₃ with g(F) = 9 and N(F) ≥ 19, using
  - an explicitly constructive algebraic function field [i]
- algebraic-geometric NRT-code AG(2;F,5P) with degPÂ =Â 3 [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(3¹⁶¹, 84, F₃, 2, 107) (dual of [(84, 2), 7, 108]-NRT-code), using
- OOA 2-folding [i] based on linear OA(3¹⁶¹, 168, F₃, 107) (dual of [168, 7, 108]-code), using
  - (u,Â uâˆ’v,Â u+v+w)-construction [i] based on
    1. linear OA(3⁵⁰, 56, F₃, 35) (dual of [56, 6, 36]-code), using
      - dual code (with bound on d by constructionÂ Y1) [i] based on
        linear OA(3⁶, 56, F₃, 3) (dual of [56, 50, 4]-code or 56-cap in PG(5,3)), using
        the Hill cap [i]
        nonexistence of linear OA(3⁵, 21, F₃, 3) (dual of [21, 16, 4]-code or 21-cap in PG(4,3)), because
        20 is the largest size of a cap in PG(4,Â 3) [i]
    2. linear OA(3⁵⁵, 56, F₃, 53) (dual of [56, 1, 54]-code), using
      - strength reduction [i] based on linear OA(3⁵⁵, 56, F₃, 55) (dual of [56, 1, 56]-code or 56-arc in PG(54,3)), using
        dual of repetition code with length 56 [i]
    3. linear OA(3⁵⁶, 56, F₃, 56) (dual of [56, 0, 57]-code or 56-arc in PG(55,3)), using
      - complete OA / dual of code with only one code word [i]
