Linear OOA(2⁷⁵, 31, F₂, 3, 39) (dual of [(31, 3), 18, 40]-NRT-code), using 1 times NRT-code embedding in larger space based on linear OOA(2⁷², 30, F₂, 3, 39) (dual of [(30, 3), 18, 40]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4²¹, 10, F₄, 3, 19) (dual of [(10, 3), 9, 20]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(3;F,10P) [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]
