MinT - Best Known (115, 115+123, s)-Nets in Base 4

Best Known (115, 115+123, s)-Nets in Base 4

(115, 115+123, 130)-Net over F₄ — Constructive and digital

Digital (115, 238, 130)-net over F₄, using

t-expansion [i] based on digital (105, 238, 130)-net over F₄, using
- net from sequence [i] based on digital (105, 129)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 105 and N(F) ≥ 130, using
    - T₇ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(115, 115+123, 168)-Net over F₄ — Digital

Digital (115, 238, 168)-net over F₄, using

net from sequence [i] based on digital (115, 167)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 115 and N(F) ≥ 168, using
  - Drinfeld modules of rank 1 [i]

(115, 115+123, 1665)-Net in Base 4 — Upper bound on s

There is no (115, 238, 1666)-net in base 4, because

1 times m-reduction [i] would yield (115, 237, 1666)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 50236 005713 405331 507310 972971 273037 727962 566868 454660 107438 981916 523371 397992 985948 352408 114637 213888 792513 452258 436486 471124 005810 339485 322080 > 4²³⁷ [i]
