Best Known (248−148, 248, s)-Nets in Base 3

(248−148, 248, 67)-Net over F₃ — Constructive and digital

Digital (100, 248, 67)-net over F₃, using

net from sequence [i] based on digital (100, 66)-sequence over F₃, using
- base reduction for sequences [i] based on digital (17, 66)-sequence over F₉, using
  - s-reduction based on digital (17, 73)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 17 and N(F) ≥ 74, using
      - a function field by GarcÃa and Quoos [i]

(248−148, 248, 96)-Net over F₃ — Digital

Digital (100, 248, 96)-net over F₃, using

(248−148, 248, 493)-Net in Base 3 — Upper bound on s

There is no (100, 248, 494)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21797 587472 376414 097343 752027 644505 608069 147851 998307 641272 054990 596675 486705 401231 280699 950930 775287 887694 202380 372269 > 3²⁴⁸ [i]
