Linear OOA(128⁶⁸, 438, F₁₂₈, 4, 38) (dual of [(438, 4), 1684, 39]-NRT-code), using strength reduction based on linear OOA(128⁶⁸, 438, F₁₂₈, 4, 39) (dual of [(438, 4), 1684, 40]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(128²⁰, 150, F₁₂₈, 4, 19) (dual of [(150, 4), 580, 20]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(4;F,580P) [i] based on function field F/F₁₂₈ with g(F) = 1 and N(F) ≥ 150, using
    - a function field by SÃ©mirat [i]
2. linear OOA(128⁴⁸, 288, F₁₂₈, 4, 39) (dual of [(288, 4), 1104, 40]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(4;F,1112P) [i] based on function field F/F₁₂₈ with g(F) = 9 and N(F) ≥ 288, using
