Linear OOA(2⁹⁸, 30, F₂, 4, 44) (dual of [(30, 4), 22, 45]-NRT-code), using OOA 2-folding based on linear OOA(2⁹⁸, 60, F₂, 2, 44) (dual of [(60, 2), 22, 45]-NRT-code), using

strength reduction [i] based on linear OOA(2⁹⁸, 60, F₂, 2, 45) (dual of [(60, 2), 22, 46]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4²⁹, 20, F₄, 2, 22) (dual of [(20, 2), 11, 23]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(4²⁹, 21, F₄, 2, 22) (dual of [(21, 2), 13, 23]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,19P) [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, using
        an explicitly constructive algebraic function field [i]
  2. linear OA(2¹, 3, F₂, 1) (dual of [3, 2, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
