Linear OA(4⁸⁷, 108, F₄, 46) (dual of [108, 21, 47]-code), using strength reduction based on linear OA(4⁸⁷, 108, F₄, 47) (dual of [108, 21, 48]-code), using

concatenation of two codes [i] based on
1. linear OA(64¹¹, 18, F₆₄, 11) (dual of [18, 7, 12]-code or 18-arc in PG(10,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹¹, 64, F₆₄, 11) (dual of [64, 53, 12]-code or 64-arc in PG(10,64)), using
    - Reedâ€“Solomon code RS(53,64) [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]
