Best Known (50, 50+9, s)-Nets in Base 8
(50, 50+9, 2097150)-Net over F8 — Constructive and digital
Digital (50, 59, 2097150)-net over F8, using
- 82 times duplication [i] based on digital (48, 57, 2097150)-net over F8, using
- net defined by OOA [i] based on linear OOA(857, 2097150, F8, 9, 9) (dual of [(2097150, 9), 18874293, 10]-NRT-code), using
- OOA 4-folding and stacking with additional row [i] based on linear OA(857, 8388601, F8, 9) (dual of [8388601, 8388544, 10]-code), using
- discarding factors / shortening the dual code based on linear OA(857, large, F8, 9) (dual of [large, large−57, 10]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 16777215 = 88−1, defining interval I = [0,8], and designed minimum distance d ≥ |I|+1 = 10 [i]

(50, 50+9, large)-Net in Base 8 — Upper bound on s
There is no (50, 59, large)-net in base 8, because
- 7 times m-reduction [i] would yield (50, 52, large)-net in base 8, but
