Linear OA(4²²⁴, 245, F₄, 138) (dual of [245, 21, 139]-code), using 1 times truncation based on linear OA(4²²⁵, 246, F₄, 139) (dual of [246, 21, 140]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁴, 41, F₆₄, 34) (dual of [41, 7, 35]-code or 41-arc in PG(33,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁴, 64, F₆₄, 34) (dual of [64, 30, 35]-code or 64-arc in PG(33,64)), using
    - Reedâ€“Solomon code RS(30,64) [i]
2. linear OA(4³, 6, F₄, 3) (dual of [6, 3, 4]-code or 6-arc in PG(2,4) or 6-cap in PG(2,4)), using
  - hyperoval in PG(2,Â 4) [i]
  - the Hexacode [i]
