Linear OOA(2²⁴⁷, 258, F₂, 2, 63) (dual of [(258, 2), 269, 64]-NRT-code), using 2¹ times duplication based on linear OOA(2²⁴⁶, 258, F₂, 2, 63) (dual of [(258, 2), 270, 64]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(32³², 43, F₃₂, 2, 31) (dual of [(43, 2), 54, 32]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(32³², 44, F₃₂, 2, 31) (dual of [(44, 2), 56, 32]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,56P) [i] based on function field F/F₃₂ with g(F) = 1 and N(F) ≥ 44, using
      - a function field by SÃ©mirat [i]
2. linear OA(2¹, 6, F₂, 1) (dual of [6, 5, 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]
