Linear OA(6449, 262152, F64, 15) (dual of [262152, 262103, 16]-code), using construction X applied to C([0,7]) ⊂ C([1,7]) based on
  1. linear OA(6443, 262145, F64, 15) (dual of [262145, 262102, 16]-code), using the expurgated narrow-sense BCH-code C(I) with length 262145 | 646−1, defining interval I = [0,7], and minimum distance d ≥ |{−7,−6,…,7}|+1 = 16 (BCH-bound) [i]
  2. linear OA(6442, 262145, F64, 8) (dual of [262145, 262103, 9]-code), using the narrow-sense BCH-code C(I) with length 262145 | 646−1, defining interval I = [1,7], and minimum distance d ≥ |{−7,−5,−3,…,7}|+1 = 9 (BCH-bound) [i]
