Linear OA(3¹⁶⁶, 178, F₃, 99) (dual of [178, 12, 100]-code), using 2 times truncation based on linear OA(3¹⁶⁸, 180, F₃, 101) (dual of [180, 12, 102]-code), using

concatenation of two codes [i] based on
1. linear OA(27¹⁶, 20, F₂₇, 16) (dual of [20, 4, 17]-code or 20-arc in PG(15,27)), using
  - discarding factors / shortening the dual code based on linear OA(27¹⁶, 27, F₂₇, 16) (dual of [27, 11, 17]-code or 27-arc in PG(15,27)), using
    - Reedâ€“Solomon code RS(11,27) [i]
