Linear OOA(4²³², 140, F₄, 2, 130) (dual of [(140, 2), 48, 131]-NRT-code), using strength reduction based on linear OOA(4²³², 140, F₄, 2, 131) (dual of [(140, 2), 48, 132]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16⁴⁶, 35, F₁₆, 2, 43) (dual of [(35, 2), 24, 44]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(16⁴⁶, 38, F₁₆, 2, 43) (dual of [(38, 2), 30, 44]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,32P) [i] based on function field F/F₁₆ with g(F) = 3 and N(F) ≥ 38, using
      - a function field by SÃ©mirat [i]
2. linear OA(4², 4, F₄, 2) (dual of [4, 2, 3]-code or 4-arc in PG(1,4)), using
  - Reedâ€“Solomon code RS(2,4) [i]
