Linear OOA(2¹³⁹, 63, F₂, 3, 60) (dual of [(63, 3), 50, 61]-NRT-code), using strength reduction based on linear OOA(2¹³⁹, 63, F₂, 3, 63) (dual of [(63, 3), 50, 64]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4³⁸, 21, F₄, 3, 31) (dual of [(21, 3), 25, 32]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(3;F,31P) [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, using
    - an explicitly constructive algebraic function field [i]
2. linear OA(2¹, 3, F₂, 1) (dual of [3, 2, 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]
