Linear OOA(2²²⁸, 139, F₂, 2, 91) (dual of [(139, 2), 50, 92]-NRT-code), using 2 step truncation based on linear OOA(2²³⁰, 140, F₂, 2, 93) (dual of [(140, 2), 50, 94]-NRT-code), using

strength reduction [i] based on linear OOA(2²³⁰, 140, F₂, 2, 94) (dual of [(140, 2), 50, 95]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32¹⁸, 28, F₃₂, 18) (dual of [28, 10, 19]-code or 28-arc in PG(17,32)), using
    - discarding factors / shortening the dual code based on linear OA(32¹⁸, 32, F₃₂, 18) (dual of [32, 14, 19]-code or 32-arc in PG(17,32)), using
      - Reedâ€“Solomon code RS(14,32) [i]
  2. linear OOA(2⁵, 5, F₂, 2, 4) (dual of [(5, 2), 5, 5]-NRT-code), using
