Linear OA(5¹²⁸, 170, F₅, 64) (dual of [170, 42, 65]-code), using 1 times truncation based on linear OA(5¹²⁹, 171, F₅, 65) (dual of [171, 42, 66]-code), using

concatenation of two codes [i] based on
1. linear OA(25³⁶, 57, F₂₅, 32) (dual of [57, 21, 33]-code), using
  - discarding factors / shortening the dual code based on linear OA(25³⁶, 65, F₂₅, 32) (dual of [65, 29, 33]-code), using
    - algebraic-geometric code AG(F,32P) [i] based on function field F/F₂₅ with g(F) = 4 and N(F) ≥ 66, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(5¹, 3, F₅, 1) (dual of [3, 2, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(5¹, s, F₅, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
