Linear OA(2163, 276, F2, 41) (dual of [276, 113, 42]-code), using construction X applied to C([0,20]) ⊂ C([1,20]) based on
- linear OA(2145, 257, F2, 41) (dual of [257, 112, 42]-code), using the expurgated narrow-sense BCH-code C(I) with length 257 | 216−1, defining interval I = [0,20], and minimum distance d ≥ |{−20,−19,…,20}|+1 = 42 (BCH-bound) [i]
- linear OA(2144, 257, F2, 22) (dual of [257, 113, 23]-code), using the narrow-sense BCH-code C(I) with length 257 | 216−1, defining interval I = [1,20], and minimum distance d ≥ |{1,2,…,20}| + |{0,118,236}| = 23 (simple Roos-bound) [i]
