Linear OOA(3²⁰², 140, F₃, 2, 86) (dual of [(140, 2), 78, 87]-NRT-code), using strength reduction based on linear OOA(3²⁰², 140, F₃, 2, 87) (dual of [(140, 2), 78, 88]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(27⁴⁴, 35, F₂₇, 2, 43) (dual of [(35, 2), 26, 44]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(27⁴⁴, 38, F₂₇, 2, 43) (dual of [(38, 2), 32, 44]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,32P) [i] based on function field F/F₂₇ with g(F) = 1 and N(F) ≥ 38, using
      - a function field by SÃ©mirat [i]
2. linear OA(3¹, 4, F₃, 1) (dual of [4, 3, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
