Linear OA(25630, 267, F256, 21) (dual of [267, 237, 22]-code), using construction X applied to C([0,10]) ⊂ C([1,10]) based on
- linear OA(25621, 257, F256, 21) (dual of [257, 236, 22]-code or 257-arc in PG(20,256)), using the expurgated narrow-sense BCH-code C(I) with length 257 | 2562−1, defining interval I = [0,10], and minimum distance d ≥ |{−10,−9,…,10}|+1 = 22 (BCH-bound) [i]
- linear OA(25620, 257, F256, 11) (dual of [257, 237, 12]-code), using the narrow-sense BCH-code C(I) with length 257 | 2562−1, defining interval I = [1,10], and minimum distance d ≥ |{1,2,…,10}| + |{−11,0}| = 12 (simple Roos-bound) [i]
