Linear OOA(2²⁵⁴, 137, F₂, 4, 61) (dual of [(137, 4), 294, 62]-NRT-code), using OOA 2-folding based on linear OOA(2²⁵⁴, 274, F₂, 2, 61) (dual of [(274, 2), 294, 62]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(2²⁵⁴, 275, F₂, 2, 61) (dual of [(275, 2), 296, 62]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(16³⁶, 55, F₁₆, 2, 30) (dual of [(55, 2), 74, 31]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(16³⁶, 64, F₁₆, 2, 30) (dual of [(64, 2), 92, 31]-NRT-code), using
      - algebraic-geometric NRT-code AG(2;F,97P) [i] based on function field F/F₁₆ with g(F) = 6 and N(F) ≥ 65, using
        the Hermitian function field over F₁₆ [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
