Linear OOA(2²⁰⁸, 72, F₂, 3, 141) (dual of [(72, 3), 8, 142]-NRT-code), using 9 step truncation based on linear OOA(2²¹⁷, 75, F₂, 3, 150) (dual of [(75, 3), 8, 151]-NRT-code), using

strength reduction [i] based on linear OOA(2²¹⁷, 75, F₂, 3, 153) (dual of [(75, 3), 8, 154]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(16¹³, 15, F₁₆, 13) (dual of [15, 2, 14]-code or 15-arc in PG(12,16)), using
    - discarding factors / shortening the dual code based on linear OA(16¹³, 16, F₁₆, 13) (dual of [16, 3, 14]-code or 16-arc in PG(12,16)), using
      - Reedâ€“Solomon code RS(3,16) [i]
  2. linear OOA(2¹¹, 5, F₂, 3, 10) (dual of [(5, 3), 4, 11]-NRT-code), using
