Linear OA(6451, 76, F64, 41) (dual of [76, 25, 42]-code), using construction X applied to C([0,20]) ⊂ C([1,20]) based on
  1. linear OA(6441, 65, F64, 41) (dual of [65, 24, 42]-code or 65-arc in PG(40,64)), using the expurgated narrow-sense BCH-code C(I) with length 65 | 642−1, defining interval I = [0,20], and minimum distance d ≥ |{−20,−19,…,20}|+1 = 42 (BCH-bound) [i]
  2. linear OA(6440, 65, F64, 30) (dual of [65, 25, 31]-code), using the narrow-sense BCH-code C(I) with length 65 | 642−1, defining interval I = [1,20], and minimum distance d ≥ |{1,2,…,11}| + |{0,22,44,…,−12}∖{22,23,24,25,26,27,28,29,30,31}| = 31 (general Roos-bound) [i]
