Digital (53, 72, 3045)-net over F7, using embedding of OOA with Gilbert–Varšamov bound based on linear OA(772, 3045, F7, 19) (dual of [3045, 2973, 20]-code), using
- 633 step Varšamov–Edel lengthening with (ri) = (2, 4 times 0, 1, 16 times 0, 1, 45 times 0, 1, 102 times 0, 1, 188 times 0, 1, 272 times 0) [i] based on linear OA(765, 2405, F7, 19) (dual of [2405, 2340, 20]-code), using
- construction X applied to Ce(18) ⊂ Ce(17) [i] based on
- linear OA(765, 2401, F7, 19) (dual of [2401, 2336, 20]-code), using an extension Ce(18) of the primitive narrow-sense BCH-code C(I) with length 2400 = 74−1, defining interval I = [1,18], and designed minimum distance d ≥ |I|+1 = 19 [i]
