Linear OOA(2⁴⁵, 30, F₂, 2, 21) (dual of [(30, 2), 15, 22]-NRT-code), using 2¹ times duplication based on linear OOA(2⁴⁴, 30, F₂, 2, 21) (dual of [(30, 2), 16, 22]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4¹², 10, F₄, 2, 10) (dual of [(10, 2), 8, 11]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,9P) [i] based on function field F/F₄ with g(F) = 2 and N(F) ≥ 10, 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]
