Linear OA(9¹³⁷, 159, F₉, 88) (dual of [159, 22, 89]-code), using 1 times truncation based on linear OA(9¹³⁸, 160, F₉, 89) (dual of [160, 22, 90]-code), using

concatenation of two codes [i] based on
1. linear OA(81²⁹, 40, F₈₁, 29) (dual of [40, 11, 30]-code or 40-arc in PG(28,81)), using
  - discarding factors / shortening the dual code based on linear OA(81²⁹, 81, F₈₁, 29) (dual of [81, 52, 30]-code or 81-arc in PG(28,81)), using
    - Reedâ€“Solomon code RS(52,81) [i]
2. linear OA(9², 4, F₉, 2) (dual of [4, 2, 3]-code or 4-arc in PG(1,9)), using
  - discarding factors / shortening the dual code based on linear OA(9², 9, F₉, 2) (dual of [9, 7, 3]-code or 9-arc in PG(1,9)), using
    - Reedâ€“Solomon code RS(7,9) [i]
