Linear OOA(2²⁴³, 87, F₂, 3, 140) (dual of [(87, 3), 18, 141]-NRT-code), using 7 step truncation based on linear OOA(2²⁵⁰, 90, F₂, 3, 147) (dual of [(90, 3), 20, 148]-NRT-code), using

strength reduction [i] based on linear OOA(2²⁵⁰, 90, F₂, 3, 149) (dual of [(90, 3), 20, 150]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32¹⁴, 18, F₃₂, 14) (dual of [18, 4, 15]-code or 18-arc in PG(13,32)), using
    - discarding factors / shortening the dual code based on linear OA(32¹⁴, 32, F₃₂, 14) (dual of [32, 18, 15]-code or 32-arc in PG(13,32)), using
      - Reedâ€“Solomon code RS(18,32) [i]
  2. linear OOA(2¹⁰, 5, F₂, 3, 9) (dual of [(5, 3), 5, 10]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,5P) [i] based on function field F/F₂ with g(F) = 1 and N(F) ≥ 5, using
      - an explicitly constructive algebraic function field [i]
