linear OOA(3⁵⁷, 26, F₃, 4, 42) (dual of [(26, 4), 47, 43]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(3⁵⁷, 28, F₃, 4, 42) (dual of [(28, 4), 55, 43]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(4;F,69P) [i] based on function field F/F₃ with g(F) = 15 and N(F) ≥ 28, using
    - an explicitly constructive algebraic function field [i]
