Linear OA(936, 49, F9, 21) (dual of [49, 13, 22]-code), using construction X applied to C([0,10]) ⊂ C([1,10]) based on
- linear OA(929, 41, F9, 21) (dual of [41, 12, 22]-code), using the expurgated narrow-sense BCH-code C(I) with length 41 | 94−1, defining interval I = [0,10], and minimum distance d ≥ |{−10,−9,…,10}|+1 = 22 (BCH-bound) [i]
- linear OA(928, 41, F9, 13) (dual of [41, 13, 14]-code), using the narrow-sense BCH-code C(I) with length 41 | 94−1, defining interval I = [1,10], and minimum distance d ≥ |{1,2,…,7}| + |{3,13,23,…,0}∖{−20,11,−19,12,−18,13}| = 14 (general Roos-bound) [i]
