Linear OA(9¹³⁰, 144, F₉, 90) (dual of [144, 14, 91]-code), using 1 times truncation based on linear OA(9¹³¹, 145, F₉, 91) (dual of [145, 14, 92]-code), using

concatenation of two codes [i] based on
1. linear OA(81²², 29, F₈₁, 22) (dual of [29, 7, 23]-code or 29-arc in PG(21,81)), using
  - discarding factors / shortening the dual code based on linear OA(81²², 81, F₈₁, 22) (dual of [81, 59, 23]-code or 81-arc in PG(21,81)), using
    - Reedâ€“Solomon code RS(59,81) [i]
2. linear OA(9³, 5, F₉, 3) (dual of [5, 2, 4]-code or 5-arc in PG(2,9) or 5-cap in PG(2,9)), using
  - discarding factors / shortening the dual code based on linear OA(9³, 9, F₉, 3) (dual of [9, 6, 4]-code or 9-arc in PG(2,9) or 9-cap in PG(2,9)), using
    - Reedâ€“Solomon code RS(6,9) [i]
