Digital (55, 75, 2893)-net over F7, using embedding of OOA with Gilbert–Varšamov bound based on linear OA(775, 2893, F7, 20) (dual of [2893, 2818, 21]-code), using
- 482 step Varšamov–Edel lengthening with (ri) = (2, 5 times 0, 1, 25 times 0, 1, 71 times 0, 1, 147 times 0, 1, 229 times 0) [i] based on linear OA(769, 2405, F7, 20) (dual of [2405, 2336, 21]-code), using
- construction X applied to Ce(19) ⊂ Ce(18) [i] based on
- linear OA(769, 2401, F7, 20) (dual of [2401, 2332, 21]-code), using an extension Ce(19) of the primitive narrow-sense BCH-code C(I) with length 2400 = 74−1, defining interval I = [1,19], and designed minimum distance d ≥ |I|+1 = 20 [i]
