Linear OOA(2²⁴⁴, 220, F₂, 2, 70) (dual of [(220, 2), 196, 71]-NRT-code), using strength reduction based on linear OOA(2²⁴⁴, 220, F₂, 2, 71) (dual of [(220, 2), 196, 72]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16³⁹, 44, F₁₆, 2, 35) (dual of [(44, 2), 49, 36]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(16³⁹, 45, F₁₆, 2, 35) (dual of [(45, 2), 51, 36]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,54P) [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 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]
