Linear OA(4²⁵⁵, 312, F₄, 134) (dual of [312, 57, 135]-code), using strength reduction based on linear OA(4²⁵⁵, 312, F₄, 135) (dual of [312, 57, 136]-code), using

concatenation of two codes [i] based on
1. linear OA(64³³, 52, F₆₄, 33) (dual of [52, 19, 34]-code or 52-arc in PG(32,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³³, 64, F₆₄, 33) (dual of [64, 31, 34]-code or 64-arc in PG(32,64)), using
    - Reedâ€“Solomon code RS(31,64) [i]
