Linear OOA(4²¹⁰, 107, F₄, 2, 177) (dual of [(107, 2), 4, 178]-NRT-code), using juxtaposition based on

linear OOA(4²², 13, F₄, 2, 19) (dual of [(13, 2), 4, 20]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(4²², 14, F₄, 2, 19) (dual of [(14, 2), 6, 20]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,8P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, using
    - an explicitly constructive algebraic function field [i]
