Best Known (50, 50+8, s)-Nets in Base 9

(50, 50+8, 4194300)-Net over F₉ — Constructive and digital

Digital (50, 58, 4194300)-net over F₉, using

net defined by OOA [i] based on linear OOA(9⁵⁸, 4194300, F₉, 10, 8) (dual of [(4194300, 10), 41942942, 9]-NRT-code), using
- OOA 2-folding and stacking with additional row [i] based on linear OOA(9⁵⁸, 8388601, F₉, 2, 8) (dual of [(8388601, 2), 16777144, 9]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(9⁵⁸, 8388602, F₉, 2, 8) (dual of [(8388602, 2), 16777146, 9]-NRT-code), using
    - trace code [i] based on linear OOA(81²⁹, 4194301, F₈₁, 2, 8) (dual of [(4194301, 2), 8388573, 9]-NRT-code), using
      - OOA 2-folding [i] based on linear OA(81²⁹, 8388602, F₈₁, 8) (dual of [8388602, 8388573, 9]-code), using
        discarding factors / shortening the dual code based on linear OA(81²⁹, large, F₈₁, 8) (dual of [large, large−29, 9]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 21523360Â | 81⁴âˆ’1, defining interval IÂ =Â [0,7], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 9 [i]

(50, 50+8, large)-Net over F₉ — Digital

Digital (50, 58, large)-net over F₉, using

9⁴ times duplication [i] based on digital (46, 54, large)-net over F₉, using
- Gilbertâ€“VarÅ¡amov bound [i]

(50, 50+8, large)-Net in Base 9 — Upper bound on s

There is no (50, 58, large)-net in base 9, because

6 times m-reduction [i] would yield (50, 52, large)-net in base 9, but
- mutually orthogonal hypercube bound [i]
