Linear OOA(4²⁵¹, 85, F₄, 3, 214) (dual of [(85, 3), 4, 215]-NRT-code), using strength reduction based on linear OOA(4²⁵¹, 85, F₄, 3, 216) (dual of [(85, 3), 4, 217]-NRT-code), using

juxtaposition [i] based on
1. linear OOA(4²⁰, 8, F₄, 3, 19) (dual of [(8, 3), 4, 20]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(4²⁰, 9, F₄, 3, 19) (dual of [(9, 3), 7, 20]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,7P) [i] based on function field F/F₄ with g(F) = 1 and N(F) ≥ 9, using
      - the Hermitian function field over F₄ [i]
