Linear OOA(3²³⁰, 220, F₃, 2, 72) (dual of [(220, 2), 210, 73]-NRT-code), using strength reduction based on linear OOA(3²³⁰, 220, F₃, 2, 73) (dual of [(220, 2), 210, 74]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(27⁴⁰, 55, F₂₇, 2, 36) (dual of [(55, 2), 70, 37]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(27⁴⁰, 64, F₂₇, 2, 36) (dual of [(64, 2), 88, 37]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,91P) [i] based on function field F/F₂₇ with g(F) = 4 and N(F) ≥ 64, 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]
