Linear OA(3¹⁶⁹, 198, F₃, 81) (dual of [198, 29, 82]-code), using 5 step VarÅ¡amovâ€“Edel lengthening with (r_i)Â = (2, 1, 1, 1, 1) based on linear OA(3¹⁶³, 187, F₃, 81) (dual of [187, 24, 82]-code), using

2 times truncation [i] based on linear OA(3¹⁶⁵, 189, F₃, 83) (dual of [189, 24, 84]-code), using
- concatenation of two codes [i] based on
  1. linear OA(27¹³, 21, F₂₇, 13) (dual of [21, 8, 14]-code or 21-arc in PG(12,27)), using
    - discarding factors / shortening the dual code based on linear OA(27¹³, 27, F₂₇, 13) (dual of [27, 14, 14]-code or 27-arc in PG(12,27)), using
      - Reedâ€“Solomon code RS(14,27) [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]
