Linear OA(3¹⁸⁴, 220, F₃, 82) (dual of [220, 36, 83]-code), using strength reduction based on linear OA(3¹⁸⁴, 220, F₃, 83) (dual of [220, 36, 84]-code), using

concatenation of two codes [i] based on
1. linear OA(81¹³, 22, F₈₁, 13) (dual of [22, 9, 14]-code or 22-arc in PG(12,81)), using
  - discarding factors / shortening the dual code based on linear OA(81¹³, 81, F₈₁, 13) (dual of [81, 68, 14]-code or 81-arc in PG(12,81)), using
    - Reedâ€“Solomon code RS(68,81) [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]
