Linear OOA(2⁹⁶, 60, F₂, 2, 42) (dual of [(60, 2), 24, 43]-NRT-code), using strength reduction based on linear OOA(2⁹⁶, 60, F₂, 2, 43) (dual of [(60, 2), 24, 44]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4²⁸, 20, F₄, 2, 21) (dual of [(20, 2), 12, 22]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(4²⁸, 21, F₄, 2, 21) (dual of [(21, 2), 14, 22]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,20P) [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, 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]
