Linear OA(780, 85, F7, 49) (dual of [85, 5, 50]-code), using construction X applied to C([0,44]) ⊂ C([1,44]) based on
- linear OA(776, 80, F7, 49) (dual of [80, 4, 50]-code), using the expurgated narrow-sense BCH-code C(I) with length 80 | 74−1, defining interval I = [0,44], and minimum distance d ≥ |{4,13,22,…,36}|+1 = 50 (BCH-bound) [i]
- linear OA(775, 80, F7, 44) (dual of [80, 5, 45]-code), using the narrow-sense BCH-code C(I) with length 80 | 74−1, defining interval I = [1,44], and designed minimum distance d ≥ |I|+1 = 45 [i]
