Linear OA(4¹⁹⁴, 202, F₄, 134) (dual of [202, 8, 135]-code), using strength reduction based on linear OA(4¹⁹⁴, 202, F₄, 135) (dual of [202, 8, 136]-code), using

juxtaposition [i] based on
1. linear OA(4⁵⁷, 65, F₄, 43) (dual of [65, 8, 44]-code), using
  - the expurgated narrow-sense BCH-code C(I) with length 65Â | 4⁶âˆ’1, defining interval IÂ =Â [0,21], and minimum distance dÂ â‰¥ |{−21,−20,…,21}|+1Â =Â 44 (BCH-bound) [i]
2. linear OA(4¹²⁹, 137, F₄, 91) (dual of [137, 8, 92]-code), using
  - juxtaposition [i] based on
    1. linear OA(4⁵⁷, 65, F₄, 43) (dual of [65, 8, 44]-code) (see above)
    2. linear OA(4⁶⁴, 72, F₄, 47) (dual of [72, 8, 48]-code), using
      - BCH codes lengthened with UEP codes [i]
