Linear OA(4²⁴³, 300, F₄, 126) (dual of [300, 57, 127]-code), using strength reduction based on linear OA(4²⁴³, 300, F₄, 127) (dual of [300, 57, 128]-code), using

concatenation of two codes [i] based on
1. linear OA(64³¹, 50, F₆₄, 31) (dual of [50, 19, 32]-code or 50-arc in PG(30,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³¹, 64, F₆₄, 31) (dual of [64, 33, 32]-code or 64-arc in PG(30,64)), using
    - Reedâ€“Solomon code RS(33,64) [i]
