(27, 27+8, 8191)-Net over F8 — Constructive and digital
Digital (27, 35, 8191)-net over F8, using
- net defined by OOA [i] based on linear OOA(835, 8191, F8, 8, 8) (dual of [(8191, 8), 65493, 9]-NRT-code), using
- OA 4-folding and stacking [i] based on linear OA(835, 32764, F8, 8) (dual of [32764, 32729, 9]-code), using
- discarding factors / shortening the dual code based on linear OA(835, 32767, F8, 8) (dual of [32767, 32732, 9]-code), using
- 1 times truncation [i] based on linear OA(836, 32768, F8, 9) (dual of [32768, 32732, 10]-code), using
- an extension Ce(8) of the primitive narrow-sense BCH-code C(I) with length 32767 = 85−1, defining interval I = [1,8], and designed minimum distance d ≥ |I|+1 = 9 [i]

(27, 27+8, large)-Net in Base 8 — Upper bound on s
There is no (27, 35, large)-net in base 8, because
- 6 times m-reduction [i] would yield (27, 29, large)-net in base 8, but
