Linear OA(3²⁰⁹, 369, F₃, 68) (dual of [369, 160, 69]-code), using 1 times truncation based on linear OA(3²¹⁰, 370, F₃, 69) (dual of [370, 160, 70]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁴, 74, F₈₁, 34) (dual of [74, 40, 35]-code or 74-arc in PG(33,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³⁴, 81, F₈₁, 34) (dual of [81, 47, 35]-code or 81-arc in PG(33,81)), using
    - Reedâ€“Solomon code RS(47,81) [i]
2. linear OA(3¹, 5, F₃, 1) (dual of [5, 4, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
