Best Known (64, 147, s)-Nets in Base 9

(64, 147, 165)-Net over F₉ — Constructive and digital

Digital (64, 147, 165)-net over F₉, using

net from sequence [i] based on digital (64, 164)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 64 and N(F) ≥ 165, using
  - T₄ from the second tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(64, 147, 192)-Net over F₉ — Digital

Digital (64, 147, 192)-net over F₉, using

t-expansion [i] based on digital (61, 147, 192)-net over F₉, using
- net from sequence [i] based on digital (61, 191)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 61 and N(F) ≥ 192, using
    - Drinfeld modules of rank 1 [i]

(64, 147, 5019)-Net in Base 9 — Upper bound on s

There is no (64, 147, 5020)-net in base 9, because

1 times m-reduction [i] would yield (64, 146, 5020)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 20 887205 100902 694870 397155 392127 425042 723898 232198 314801 327040 460888 424520 803607 215820 359410 628622 155824 602767 922930 758644 444516 476100 099553 > 9¹⁴⁶ [i]
