Linear OA(3¹⁷⁴, 210, F₃, 76) (dual of [210, 36, 77]-code), using strength reduction based on linear OA(3¹⁷⁴, 210, F₃, 77) (dual of [210, 36, 78]-code), using

concatenation of two codes [i] based on
1. linear OA(81¹², 21, F₈₁, 12) (dual of [21, 9, 13]-code or 21-arc in PG(11,81)), using
  - discarding factors / shortening the dual code based on linear OA(81¹², 81, F₈₁, 12) (dual of [81, 69, 13]-code or 81-arc in PG(11,81)), using
    - Reedâ€“Solomon code RS(69,81) [i]
2. linear OA(3⁶, 10, F₃, 5) (dual of [10, 4, 6]-code), using
  - projective code from ovoid in PG(3,Â 3) [i]
