Linear OOA(2¹²¹, 25, F₂, 6, 61) (dual of [(25, 6), 29, 62]-NRT-code), using OOA 2-folding based on linear OOA(2¹²¹, 50, F₂, 3, 61) (dual of [(50, 3), 29, 62]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(2¹²¹, 51, F₂, 3, 61) (dual of [(51, 3), 32, 62]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4³⁵, 17, F₄, 3, 30) (dual of [(17, 3), 16, 31]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,20P) [i] based on function field F/F₄ with g(F) = 5 and N(F) ≥ 17, 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]
