Linear OA(6454, 262340, F64, 15) (dual of [262340, 262286, 16]-code), using (u, u+v)-construction based on
  1. linear OA(6411, 195, F64, 7) (dual of [195, 184, 8]-code), using
    • the BCH-code C(I) with length 195 | 642−1, defining interval I = {64,86,108,…,1}, and designed minimum distance d ≥ |I|+1 = 8 [i]
  2. 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]
