Linear OA(999, 105, F9, 63) (dual of [105, 6, 64]-code), using construction X applied to C([0,31]) ⊂ C([1,31]) based on
- linear OA(977, 82, F9, 63) (dual of [82, 5, 64]-code), using the expurgated narrow-sense BCH-code C(I) with length 82 | 94−1, defining interval I = [0,31], and minimum distance d ≥ |{−31,−30,…,31}|+1 = 64 (BCH-bound) [i]
- linear OA(976, 82, F9, 40) (dual of [82, 6, 41]-code), using the narrow-sense BCH-code C(I) with length 82 | 94−1, defining interval I = [1,31], and minimum distance d ≥ |{1,2,…,14}| + |{13,40,67,…,0}∖{28,29,30,31,32,33,34,35,36,37,38,39,40}| = 41 (general Roos-bound) [i]
