Linear OA(9119, 127, F9, 90) (dual of [127, 8, 91]-code), using juxtaposition based on
  1. linear OA(910, 18, F9, 9) (dual of [18, 8, 10]-code), using
  2. linear OA(9101, 109, F9, 80) (dual of [109, 8, 81]-code), using
    • construction X applied to Ce(79) ⊂ Ce(60) [i] based on
      1. linear OA(980, 81, F9, 80) (dual of [81, 1, 81]-code or 81-arc in PG(79,9)), using an extension Ce(79) of the primitive narrow-sense BCH-code C(I) with length 80 = 92−1, defining interval I = [1,79], and designed minimum distance d ≥ |I|+1 = 80 [i]
      2. linear OA(973, 81, F9, 61) (dual of [81, 8, 62]-code), using an extension Ce(60) of the primitive narrow-sense BCH-code C(I) with length 80 = 92−1, defining interval I = [1,60], and designed minimum distance d ≥ |I|+1 = 61 [i]
