Linear OOA(2²⁴³, 63, F₂, 4, 171) (dual of [(63, 4), 9, 172]-NRT-code), using 7 step truncation based on linear OOA(2²⁵⁰, 65, F₂, 4, 178) (dual of [(65, 4), 10, 179]-NRT-code), using

strength reduction [i] based on linear OOA(2²⁵⁰, 65, F₂, 4, 179) (dual of [(65, 4), 10, 180]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32¹¹, 13, F₃₂, 11) (dual of [13, 2, 12]-code or 13-arc in PG(10,32)), using
    - discarding factors / shortening the dual code based on linear OA(32¹¹, 32, F₃₂, 11) (dual of [32, 21, 12]-code or 32-arc in PG(10,32)), using
      - Reedâ€“Solomon code RS(21,32) [i]
  2. linear OOA(2¹⁵, 5, F₂, 4, 14) (dual of [(5, 4), 5, 15]-NRT-code), using
