Digital (39, 69, 4305)-net over F64, using embedding of OOA with Gilbert–Varšamov bound based on linear OA(6469, 4305, F64, 30) (dual of [4305, 4236, 31]-code), using
- 197 step Varšamov–Edel lengthening with (ri) = (5, 1, 0, 0, 1, 8 times 0, 1, 21 times 0, 1, 49 times 0, 1, 111 times 0) [i] based on linear OA(6459, 4098, F64, 30) (dual of [4098, 4039, 31]-code), using
- construction X applied to Ce(29) ⊂ Ce(28) [i] based on
- linear OA(6459, 4096, F64, 30) (dual of [4096, 4037, 31]-code), using an extension Ce(29) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,29], and designed minimum distance d ≥ |I|+1 = 30 [i]
- 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]
- linear OA(640, 2, F64, 0) (dual of [2, 2, 1]-code), using
