Linear OA(8¹²⁸, 132, F₈, 111) (dual of [132, 4, 112]-code), using 8 times truncation based on linear OA(8¹³⁶, 140, F₈, 119) (dual of [140, 4, 120]-code), using

juxtaposition [i] based on
1. linear OA(8⁶¹, 65, F₈, 55) (dual of [65, 4, 56]-code), using
  - projective code from ovoid in PG(3,Â 8) [i]
  - the expurgated narrow-sense BCH-code C(I) with length 65Â | 8⁴âˆ’1, defining interval IÂ =Â [0,27], and minimum distance dÂ â‰¥ |{−27,−26,…,27}|+1Â =Â 56 (BCH-bound) [i]
2. linear OA(8⁷¹, 75, F₈, 63) (dual of [75, 4, 64]-code), using
  - constructionÂ X applied to C₁ âŠ‚ C₂ with C₁ a [65,1,64]-code [i] based on
    1. linear OA(8⁶¹, 65, F₈, 55) (dual of [65, 4, 56]-code), using projective code from ovoid in PG(3,Â 8) [i]
    2. linear OA(8⁷, 10, F₈, 7) (dual of [10, 3, 8]-code or 10-arc in PG(6,8)), using
