Digital (78, 97, 4660)-net over F4, using embedding of OOA with Gilbert–Varšamov bound based on linear OA(497, 4660, F4, 19) (dual of [4660, 4563, 20]-code), using
- 546 step Varšamov–Edel lengthening with (ri) = (3, 1, 0, 0, 1, 5 times 0, 1, 11 times 0, 1, 20 times 0, 1, 34 times 0, 1, 57 times 0, 1, 88 times 0, 1, 132 times 0, 1, 187 times 0) [i] based on linear OA(485, 4102, F4, 19) (dual of [4102, 4017, 20]-code), using
- construction X applied to Ce(18) ⊂ Ce(17) [i] based on
- linear OA(485, 4096, F4, 19) (dual of [4096, 4011, 20]-code), using an extension Ce(18) of the primitive narrow-sense BCH-code C(I) with length 4095 = 46−1, defining interval I = [1,18], and designed minimum distance d ≥ |I|+1 = 19 [i]
