MinT - Best Known (232−147, 232, s)-Nets in Base 4

Best Known (232−147, 232, s)-Nets in Base 4

(232−147, 232, 104)-Net over F₄ — Constructive and digital

Digital (85, 232, 104)-net over F₄, using

t-expansion [i] based on digital (73, 232, 104)-net over F₄, using
- net from sequence [i] based on digital (73, 103)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 104, using
    - F₆ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(232−147, 232, 129)-Net over F₄ — Digital

Digital (85, 232, 129)-net over F₄, using

t-expansion [i] based on digital (81, 232, 129)-net over F₄, using
- net from sequence [i] based on digital (81, 128)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 81 and N(F) ≥ 129, using
    - Drinfeld modules of rank 1 [i]

(232−147, 232, 691)-Net in Base 4 — Upper bound on s

There is no (85, 232, 692)-net in base 4, because

1 times m-reduction [i] would yield (85, 231, 692)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 093575 096161 989751 932921 358992 213827 744051 259341 294029 387343 911128 517464 078263 621979 276828 892224 137416 969132 089288 972950 065379 105793 519316 > 4²³¹ [i]
