Linear OOA(2²²⁸, 30, F₂, 8, 154) (dual of [(30, 8), 12, 155]-NRT-code), using OOA 2-folding based on linear OOA(2²²⁸, 60, F₂, 4, 154) (dual of [(60, 4), 12, 155]-NRT-code), using

strength reduction [i] based on linear OOA(2²²⁸, 60, F₂, 4, 155) (dual of [(60, 4), 12, 156]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(16¹², 15, F₁₆, 12) (dual of [15, 3, 13]-code or 15-arc in PG(11,16)), using
    - discarding factors / shortening the dual code based on linear OA(16¹², 16, F₁₆, 12) (dual of [16, 4, 13]-code or 16-arc in PG(11,16)), using
      - Reedâ€“Solomon code RS(4,16) [i]
  2. linear OOA(2¹², 4, F₂, 4, 11) (dual of [(4, 4), 4, 12]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(2¹², 5, F₂, 4, 11) (dual of [(5, 4), 8, 12]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(4;F,8P) [i] based on function field F/F₂ with g(F) = 1 and N(F) ≥ 5, using
        an explicitly constructive algebraic function field [i]
