Linear OA(4²⁵³, 260, F₄, 183) (dual of [260, 7, 184]-code), using 7 times truncation based on linear OA(4²⁶⁰, 267, F₄, 190) (dual of [267, 7, 191]-code), using

strength reduction [i] based on linear OA(4²⁶⁰, 267, F₄, 191) (dual of [267, 7, 192]-code), using
- juxtaposition [i] based on
  1. linear OA(4⁴, 11, F₄, 3) (dual of [11, 7, 4]-code or 11-cap in PG(3,4)), using
    - discarding factors / shortening the dual code based on linear OA(4⁴, 17, F₄, 3) (dual of [17, 13, 4]-code or 17-cap in PG(3,4)), using
      - ovoid in PG(3,Â 4) [i]
  2. linear OA(4²⁴⁹, 256, F₄, 187) (dual of [256, 7, 188]-code), using
    - an extension C_e(186) of the primitive narrow-sense BCH-code C(I) with length 255Â = 4⁴âˆ’1, defining interval IÂ =Â [1,186], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 187 [i]
