Digital (29, 50, 4668)-net over F64, using embedding of OOA with Gilbert–Varšamov bound based on linear OA(6450, 4668, F64, 21) (dual of [4668, 4618, 22]-code), using
- 561 step Varšamov–Edel lengthening with (ri) = (4, 0, 1, 4 times 0, 1, 16 times 0, 1, 49 times 0, 1, 137 times 0, 1, 348 times 0) [i] based on linear OA(6441, 4098, F64, 21) (dual of [4098, 4057, 22]-code), using
- construction X applied to Ce(20) ⊂ Ce(19) [i] based on
- linear OA(6441, 4096, F64, 21) (dual of [4096, 4055, 22]-code), using an extension Ce(20) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,20], and designed minimum distance d ≥ |I|+1 = 21 [i]
- linear OA(6439, 4096, F64, 20) (dual of [4096, 4057, 21]-code), using an extension Ce(19) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,19], and designed minimum distance d ≥ |I|+1 = 20 [i]
