Linear OOA(2¹¹⁹, 69, F₂, 2, 57) (dual of [(69, 2), 19, 58]-NRT-code), using 1 step truncation based on linear OOA(2¹²⁰, 70, F₂, 2, 58) (dual of [(70, 2), 20, 59]-NRT-code), using

strength reduction [i] based on linear OOA(2¹²⁰, 70, F₂, 2, 59) (dual of [(70, 2), 20, 60]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(16⁹, 14, F₁₆, 9) (dual of [14, 5, 10]-code or 14-arc in PG(8,16)), using
    - discarding factors / shortening the dual code based on linear OA(16⁹, 16, F₁₆, 9) (dual of [16, 7, 10]-code or 16-arc in PG(8,16)), using
      - Reedâ€“Solomon code RS(7,16) [i]
  2. linear OOA(2⁶, 5, F₂, 2, 5) (dual of [(5, 2), 4, 6]-NRT-code), using
