Linear OA(3²⁰⁹, 221, F₃, 126) (dual of [221, 12, 127]-code), using 4 times truncation based on linear OA(3²¹³, 225, F₃, 130) (dual of [225, 12, 131]-code), using

strength reduction [i] based on linear OA(3²¹³, 225, F₃, 131) (dual of [225, 12, 132]-code), using
- concatenation of two codes [i] based on
  1. linear OA(27²¹, 25, F₂₇, 21) (dual of [25, 4, 22]-code or 25-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]
