Linear OA(25639, 270, F256, 27) (dual of [270, 231, 28]-code), using construction X applied to C([0,13]) ⊂ C([1,13]) based on
- linear OA(25627, 257, F256, 27) (dual of [257, 230, 28]-code or 257-arc in PG(26,256)), using the expurgated narrow-sense BCH-code C(I) with length 257 | 2562−1, defining interval I = [0,13], and minimum distance d ≥ |{−13,−12,…,13}|+1 = 28 (BCH-bound) [i]
- linear OA(25626, 257, F256, 14) (dual of [257, 231, 15]-code), using the narrow-sense BCH-code C(I) with length 257 | 2562−1, defining interval I = [1,13], and minimum distance d ≥ |{−13,−11,−9,…,13}|+1 = 15 (BCH-bound) [i]
