Linear OA(3⁸⁷, 147, F₃, 32) (dual of [147, 60, 33]-code), using 1 times truncation based on linear OA(3⁸⁸, 148, F₃, 33) (dual of [148, 60, 34]-code), using

concatenation of two codes [i] based on
1. linear OA(27¹⁷, 37, F₂₇, 16) (dual of [37, 20, 17]-code), using
  - discarding factors / shortening the dual code based on linear OA(27¹⁷, 38, F₂₇, 16) (dual of [38, 21, 17]-code), using
    - extended algebraic-geometric code AG_e(F,21P) [i] based on function field F/F₂₇ with g(F) = 1 and N(F) ≥ 38, using
      - a function field by SÃ©mirat [i]
2. linear OA(3¹, 4, F₃, 1) (dual of [4, 3, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
