Linear OOA(2²⁴⁹, 124, F₂, 3, 90) (dual of [(124, 3), 123, 91]-NRT-code), using strength reduction based on linear OOA(2²⁴⁹, 124, F₂, 3, 91) (dual of [(124, 3), 123, 92]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁵², 31, F₈, 3, 45) (dual of [(31, 3), 41, 46]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁵², 34, F₈, 3, 45) (dual of [(34, 3), 50, 46]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,56P) [i] based on function field F/F₈ with g(F) = 7 and N(F) ≥ 34, using
      - a function field by SÃ©mirat [i]
