Linear OA(4²⁴⁶, 270, F₄, 150) (dual of [270, 24, 151]-code), using strength reduction based on linear OA(4²⁴⁶, 270, F₄, 151) (dual of [270, 24, 152]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁷, 45, F₆₄, 37) (dual of [45, 8, 38]-code or 45-arc in PG(36,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁷, 64, F₆₄, 37) (dual of [64, 27, 38]-code or 64-arc in PG(36,64)), using
    - Reedâ€“Solomon code RS(27,64) [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
