Linear OOA(2²¹², 180, F₂, 2, 64) (dual of [(180, 2), 148, 65]-NRT-code), using strength reduction based on linear OOA(2²¹², 180, F₂, 2, 65) (dual of [(180, 2), 148, 66]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16³⁵, 36, F₁₆, 2, 32) (dual of [(36, 2), 37, 33]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(16³⁵, 38, F₁₆, 2, 32) (dual of [(38, 2), 41, 33]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,43P) [i] based on function field F/F₁₆ with g(F) = 3 and N(F) ≥ 38, using
      - a function field by SÃ©mirat [i]
2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
