Linear OA(4²⁴⁰, 264, F₄, 146) (dual of [264, 24, 147]-code), using strength reduction based on linear OA(4²⁴⁰, 264, F₄, 147) (dual of [264, 24, 148]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁶, 44, F₆₄, 36) (dual of [44, 8, 37]-code or 44-arc in PG(35,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁶, 64, F₆₄, 36) (dual of [64, 28, 37]-code or 64-arc in PG(35,64)), using
    - Reedâ€“Solomon code RS(28,64) [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
