Linear OOA(2²¹⁸, 86, F₂, 4, 70) (dual of [(86, 4), 126, 71]-NRT-code), using OOA 2-folding based on linear OOA(2²¹⁸, 172, F₂, 2, 70) (dual of [(172, 2), 126, 71]-NRT-code), using

strength reduction [i] based on linear OOA(2²¹⁸, 172, F₂, 2, 71) (dual of [(172, 2), 126, 72]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(8⁴⁴, 43, F₈, 2, 35) (dual of [(43, 2), 42, 36]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(8⁴⁴, 45, F₈, 2, 35) (dual of [(45, 2), 46, 36]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,54P) [i] based on function field F/F₈ with g(F) = 9 and N(F) ≥ 45, using
        an explicitly constructive algebraic function field [i]
  2. linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 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]
