Linear OA(3100, 107, F3, 64) (dual of [107, 7, 65]-code), using juxtaposition based on
  1. linear OA(319, 26, F3, 13) (dual of [26, 7, 14]-code), using
    • contraction [i] based on linear OA(345, 52, F3, 27) (dual of [52, 7, 28]-code), using the expurgated narrow-sense BCH-code C(I) with length 52 | 36−1, defining interval I = [0,25], and minimum distance d ≥ |{−1,0,…,25}|+1 = 28 (BCH-bound) [i]
  2. linear OA(374, 81, F3, 50) (dual of [81, 7, 51]-code), using
    • an extension Ce(49) of the primitive narrow-sense BCH-code C(I) with length 80 = 34−1, defining interval I = [1,49], and designed minimum distance d ≥ |I|+1 = 50 [i]
