Linear OOA(4⁹¹, 48, F₄, 2, 70) (dual of [(48, 2), 5, 71]-NRT-code), using strength reduction based on linear OOA(4⁹¹, 48, F₄, 2, 71) (dual of [(48, 2), 5, 72]-NRT-code), using

generalized (u,Â u+v)-construction [i] based on
1. linear OOA(4²⁰, 12, F₄, 2, 17) (dual of [(12, 2), 4, 18]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(4²⁰, 14, F₄, 2, 17) (dual of [(14, 2), 8, 18]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,10P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, using
      - an explicitly constructive algebraic function field [i]
2. linear OOA(4²³, 12, F₄, 2, 23) (dual of [(12, 2), 1, 24]-NRT-code), using
  - dual of repetition NRT-code with length 12 [i]
3. linear OOA(4²⁴, 12, F₄, 2, 24) (dual of [(12, 2), 0, 25]-NRT-code), using
  - complete OOA / dual of NRT-code with only one code word [i]
