Linear OOA(2²⁵⁴, 154, F₂, 2, 101) (dual of [(154, 2), 54, 102]-NRT-code), using 1 step truncation based on linear OOA(2²⁵⁵, 155, F₂, 2, 102) (dual of [(155, 2), 55, 103]-NRT-code), using

strength reduction [i] based on linear OOA(2²⁵⁵, 155, F₂, 2, 104) (dual of [(155, 2), 55, 105]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32²⁰, 31, F₃₂, 20) (dual of [31, 11, 21]-code or 31-arc in PG(19,32)), using
    - discarding factors / shortening the dual code based on linear OA(32²⁰, 32, F₃₂, 20) (dual of [32, 12, 21]-code or 32-arc in PG(19,32)), using
      - Reedâ€“Solomon code RS(12,32) [i]
  2. linear OOA(2⁵, 5, F₂, 2, 4) (dual of [(5, 2), 5, 5]-NRT-code), using
