Linear OOA(4²¹⁸, 147, F₄, 2, 110) (dual of [(147, 2), 76, 111]-NRT-code), using strength reduction based on linear OOA(4²¹⁸, 147, F₄, 2, 111) (dual of [(147, 2), 76, 112]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16⁶⁰, 49, F₁₆, 2, 55) (dual of [(49, 2), 38, 56]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,42P) [i] based on function field F/F₁₆ with g(F) = 5 and N(F) ≥ 49, using
    - a function field by SÃ©mirat [i]
2. linear OA(4¹, 3, F₄, 1) (dual of [3, 2, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(4¹, s, F₄, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
