Linear OOA(2²⁴⁹, 80, F₂, 4, 108) (dual of [(80, 4), 71, 109]-NRT-code), using 3 step truncation based on linear OOA(2²⁵², 81, F₂, 4, 111) (dual of [(81, 4), 72, 112]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(64¹⁵, 27, F₆₄, 15) (dual of [27, 12, 16]-code or 27-arc in PG(14,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹⁵, 64, F₆₄, 15) (dual of [64, 49, 16]-code or 64-arc in PG(14,64)), using
    - Reedâ€“Solomon code RS(49,64) [i]
2. linear OOA(2⁶, 3, F₂, 4, 6) (dual of [(3, 4), 6, 7]-NRT-code), using
  - extended Reedâ€“Solomon NRT-code RS_e(4;6,2) [i]
