Linear OOA(2²⁵⁴, 149, F₂, 2, 106) (dual of [(149, 2), 44, 107]-NRT-code), using 1 step truncation based on linear OOA(2²⁵⁵, 150, F₂, 2, 107) (dual of [(150, 2), 45, 108]-NRT-code), using

strength reduction [i] based on linear OOA(2²⁵⁵, 150, F₂, 2, 109) (dual of [(150, 2), 45, 110]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32²¹, 30, F₃₂, 21) (dual of [30, 9, 22]-code or 30-arc in PG(20,32)), using
    - discarding factors / shortening the dual code based on linear OA(32²¹, 32, F₃₂, 21) (dual of [32, 11, 22]-code or 32-arc in PG(20,32)), using
      - Reedâ€“Solomon code RS(11,32) [i]
  2. linear OOA(2⁵, 5, F₂, 2, 4) (dual of [(5, 2), 5, 5]-NRT-code), using
