Linear OA(3²⁰⁸, 344, F₃, 70) (dual of [344, 136, 71]-code), using 1 times truncation based on linear OA(3²⁰⁹, 345, F₃, 71) (dual of [345, 136, 72]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁵, 69, F₈₁, 35) (dual of [69, 34, 36]-code or 69-arc in PG(34,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³⁵, 81, F₈₁, 35) (dual of [81, 46, 36]-code or 81-arc in PG(34,81)), using
    - Reedâ€“Solomon code RS(46,81) [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]
