Linear OA(442, 48, F4, 23) (dual of [48, 6, 24]-code), using construction X applied to C([0,20]) ⊂ C([1,20]) based on
- linear OA(440, 45, F4, 23) (dual of [45, 5, 24]-code), using the expurgated narrow-sense BCH-code C(I) with length 45 | 46−1, defining interval I = [0,20], and minimum distance d ≥ |{−2,−1,…,20}|+1 = 24 (BCH-bound) [i]
- linear OA(439, 45, F4, 20) (dual of [45, 6, 21]-code), using the narrow-sense BCH-code C(I) with length 45 | 46−1, defining interval I = [1,20], and designed minimum distance d ≥ |I|+1 = 21 [i]
