Linear OOA(6488, 2229, F64, 2, 32) (dual of [(2229, 2), 4370, 33]-NRT-code), using (u, u+v)-construction based on
  1. linear OOA(6423, 177, F64, 2, 16) (dual of [(177, 2), 331, 17]-NRT-code), using
  2. linear OOA(6465, 2052, F64, 2, 32) (dual of [(2052, 2), 4039, 33]-NRT-code), using
    • OOA 2-folding [i] based on linear OA(6465, 4104, F64, 32) (dual of [4104, 4039, 33]-code), using
      • construction X applied to Ce(31) ⊂ Ce(28) [i] based on
        1. linear OA(6463, 4096, F64, 32) (dual of [4096, 4033, 33]-code), using an extension Ce(31) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,31], and designed minimum distance d ≥ |I|+1 = 32 [i]
        2. linear OA(6457, 4096, F64, 29) (dual of [4096, 4039, 30]-code), using an extension Ce(28) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,28], and designed minimum distance d ≥ |I|+1 = 29 [i]
