Linear OOA(2¹³⁰, 121, F₂, 2, 39) (dual of [(121, 2), 112, 40]-NRT-code), using 1 times NRT-code embedding in larger space based on linear OOA(2¹²⁸, 120, F₂, 2, 39) (dual of [(120, 2), 112, 40]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16²⁰, 24, F₁₆, 2, 19) (dual of [(24, 2), 28, 20]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,28P) [i] based on function field F/F₁₆ with g(F) = 1 and N(F) ≥ 24, 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]
