Linear OA(3¹³⁹, 155, F₃, 76) (dual of [155, 16, 77]-code), using 1 times truncation based on linear OA(3¹⁴⁰, 156, F₃, 77) (dual of [156, 16, 78]-code), using

(u,Â u+v)-construction [i] based on
1. linear OA(3⁶³, 78, F₃, 38) (dual of [78, 15, 39]-code), using
  - discarding factors / shortening the dual code based on linear OA(3⁶³, 79, F₃, 38) (dual of [79, 16, 39]-code), using
    - 3 times truncation [i] based on linear OA(3⁶⁶, 82, F₃, 41) (dual of [82, 16, 42]-code), using
      - contraction [i] based on linear OA(3¹⁴⁸, 164, F₃, 83) (dual of [164, 16, 84]-code), using the BCH-code C(I) with length 164Â | 3⁸âˆ’1, defining interval IÂ =Â {0,1,…,82}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 84 [i]
