Linear OOA(2⁸⁶, 38, F₂, 3, 42) (dual of [(38, 3), 28, 43]-NRT-code), using 1 step truncation based on linear OOA(2⁸⁷, 39, F₂, 3, 43) (dual of [(39, 3), 30, 44]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4²⁴, 13, F₄, 3, 21) (dual of [(13, 3), 15, 22]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(4²⁴, 14, F₄, 3, 21) (dual of [(14, 3), 18, 22]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,20P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, 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]
