Linear OA(25615, 262, F256, 11) (dual of [262, 247, 12]-code), using construction X applied to C([0,5]) ⊂ C([1,5]) based on
  1. linear OA(25611, 257, F256, 11) (dual of [257, 246, 12]-code or 257-arc in PG(10,256)), using the expurgated narrow-sense BCH-code C(I) with length 257 | 2562−1, defining interval I = [0,5], and minimum distance d ≥ |{−5,−4,…,5}|+1 = 12 (BCH-bound) [i]
  2. linear OA(25610, 257, F256, 6) (dual of [257, 247, 7]-code), using the narrow-sense BCH-code C(I) with length 257 | 2562−1, defining interval I = [1,5], and minimum distance d ≥ |{−5,−3,−1,…,5}|+1 = 7 (BCH-bound) [i]
