Linear OA(3²¹⁶, 231, F₃, 128) (dual of [231, 15, 129]-code), using 3 times truncation based on linear OA(3²¹⁹, 234, F₃, 131) (dual of [234, 15, 132]-code), using

concatenation of two codes [i] based on
1. linear OA(27²¹, 26, F₂₇, 21) (dual of [26, 5, 22]-code or 26-arc in PG(20,27)), using
  - discarding factors / shortening the dual code based on linear OA(27²¹, 27, F₂₇, 21) (dual of [27, 6, 22]-code or 27-arc in PG(20,27)), using
    - Reedâ€“Solomon code RS(6,27) [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]
