Digital (21, 43, 1640)-net over F81, using embedding of OOA with Gilbert–Varšamov bound based on linear OOA(8143, 1640, F81, 4, 22) (dual of [(1640, 4), 6517, 23]-NRT-code), using
- OOA 4-folding [i] based on linear OA(8143, 6560, F81, 22) (dual of [6560, 6517, 23]-code), using
- discarding factors / shortening the dual code based on linear OA(8143, 6561, F81, 22) (dual of [6561, 6518, 23]-code), using
- an extension Ce(21) of the primitive narrow-sense BCH-code C(I) with length 6560 = 812−1, defining interval I = [1,21], and designed minimum distance d ≥ |I|+1 = 22 [i]
- discarding factors / shortening the dual code based on linear OA(8143, 6561, F81, 22) (dual of [6561, 6518, 23]-code), using
