Linear OOA(6485, 2229, F64, 2, 31) (dual of [(2229, 2), 4373, 32]-NRT-code), using (u, u+v)-construction based on
  1. linear OOA(6422, 177, F64, 2, 15) (dual of [(177, 2), 332, 16]-NRT-code), using
  2. linear OOA(6463, 2052, F64, 2, 31) (dual of [(2052, 2), 4041, 32]-NRT-code), using
    • OOA 2-folding [i] based on linear OA(6463, 4104, F64, 31) (dual of [4104, 4041, 32]-code), using
      • construction X applied to Ce(30) ⊂ Ce(27) [i] based on
        1. linear OA(6461, 4096, F64, 31) (dual of [4096, 4035, 32]-code), using an extension Ce(30) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,30], and designed minimum distance d ≥ |I|+1 = 31 [i]
        2. linear OA(6455, 4096, F64, 28) (dual of [4096, 4041, 29]-code), using an extension Ce(27) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,27], and designed minimum distance d ≥ |I|+1 = 28 [i]
