Linear OOA(2⁵⁸, 42, F₂, 2, 24) (dual of [(42, 2), 26, 25]-NRT-code), using strength reduction based on linear OOA(2⁵⁸, 42, F₂, 2, 25) (dual of [(42, 2), 26, 26]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4¹⁵, 14, F₄, 2, 12) (dual of [(14, 2), 13, 13]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,15P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, 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]
