Linear OOA(3¹⁵⁹, 33, F₃, 5, 105) (dual of [(33, 5), 6, 106]-NRT-code), using OOA 5-folding based on linear OA(3¹⁵⁹, 165, F₃, 105) (dual of [165, 6, 106]-code), using

discarding factors / shortening the dual code based on linear OA(3¹⁵⁹, 166, F₃, 105) (dual of [166, 7, 106]-code), using
- 2 times truncation [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]
