Linear OA(3¹⁵⁶, 180, F₃, 75) (dual of [180, 24, 76]-code), using strength reduction based on linear OA(3¹⁵⁶, 180, F₃, 77) (dual of [180, 24, 78]-code), using

concatenation of two codes [i] based on
1. linear OA(27¹², 20, F₂₇, 12) (dual of [20, 8, 13]-code or 20-arc in PG(11,27)), using
  - discarding factors / shortening the dual code based on linear OA(27¹², 27, F₂₇, 12) (dual of [27, 15, 13]-code or 27-arc in PG(11,27)), using
    - Reedâ€“Solomon code RS(15,27) [i]
2. linear OA(3⁶, 9, F₃, 5) (dual of [9, 3, 6]-code), using
  - discarding factors / shortening the dual code based on linear OA(3⁶, 10, F₃, 5) (dual of [10, 4, 6]-code), using
    - projective code from ovoid in PG(3,Â 3) [i]
