Linear OA(938, 47, F9, 23) (dual of [47, 9, 24]-code), using construction X applied to C([0,11]) ⊂ C([1,11]) based on
- linear OA(933, 41, F9, 23) (dual of [41, 8, 24]-code), using the expurgated narrow-sense BCH-code C(I) with length 41 | 94−1, defining interval I = [0,11], and minimum distance d ≥ |{−11,−10,…,11}|+1 = 24 (BCH-bound) [i]
- linear OA(932, 41, F9, 17) (dual of [41, 9, 18]-code), using the narrow-sense BCH-code C(I) with length 41 | 94−1, defining interval I = [1,11], and minimum distance d ≥ |{6,17}| + |{18,22,26,…,0}∖{9}| = 18 (general Roos-bound) [i]
