Linear OOA(4²⁰⁰, 72, F₄, 3, 135) (dual of [(72, 3), 16, 136]-NRT-code), using generalized (u,Â u+v)-construction based on

linear OOA(4⁴⁰, 18, F₄, 3, 33) (dual of [(18, 3), 14, 34]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(4⁴⁰, 21, F₄, 3, 33) (dual of [(21, 3), 23, 34]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(3;F,29P) [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, using
    - an explicitly constructive algebraic function field [i]
