Linear OOA(2²⁵², 230, F₂, 2, 70) (dual of [(230, 2), 208, 71]-NRT-code), using strength reduction based on linear OOA(2²⁵², 230, F₂, 2, 71) (dual of [(230, 2), 208, 72]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16⁴⁰, 46, F₁₆, 2, 35) (dual of [(46, 2), 52, 36]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(16⁴⁰, 49, F₁₆, 2, 35) (dual of [(49, 2), 58, 36]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,62P) [i] based on function field F/F₁₆ with g(F) = 5 and N(F) ≥ 49, using
      - a function field by SÃ©mirat [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]
