Linear OOA(2¹⁵⁸, 64, F₂, 3, 77) (dual of [(64, 3), 34, 78]-NRT-code), using 2² times duplication based on linear OOA(2¹⁵⁶, 64, F₂, 3, 77) (dual of [(64, 3), 36, 78]-NRT-code), using

1 times NRT-code embedding in larger space [i] based on linear OOA(2¹⁵³, 63, F₂, 3, 77) (dual of [(63, 3), 36, 78]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4⁴⁵, 21, F₄, 3, 38) (dual of [(21, 3), 18, 39]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,24P) [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]
