Linear OOA(3¹⁸⁸, 136, F₃, 2, 70) (dual of [(136, 2), 84, 71]-NRT-code), using OOA 2-folding based on linear OA(3¹⁸⁸, 272, F₃, 70) (dual of [272, 84, 71]-code), using

strength reduction [i] based on linear OA(3¹⁸⁸, 272, F₃, 71) (dual of [272, 84, 72]-code), using
- concatenation of two codes [i] based on
  1. linear OA(27⁴⁰, 68, F₂₇, 35) (dual of [68, 28, 36]-code), using
    - extended algebraic-geometric code AG_e(F,32P) [i] based on function field F/F₂₇ with g(F) = 5 and N(F) ≥ 68, using
      - a function field by SÃ©mirat [i]
  2. linear OA(3¹, 4, F₃, 1) (dual of [4, 3, 2]-code), using
