Best Known (82, 82+115, s)-Nets in Base 4

(82, 82+115, 104)-Net over F₄ — Constructive and digital

Digital (82, 197, 104)-net over F₄, using

t-expansion [i] based on digital (73, 197, 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]

(82, 82+115, 129)-Net over F₄ — Digital

Digital (82, 197, 129)-net over F₄, using

t-expansion [i] based on digital (81, 197, 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]

(82, 82+115, 819)-Net in Base 4 — Upper bound on s

There is no (82, 197, 820)-net in base 4, because

1 times m-reduction [i] would yield (82, 196, 820)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10670 354847 515070 925014 683626 420430 524307 136650 696750 598750 802786 973115 238350 933799 637468 022906 493757 345894 623291 727584 > 4¹⁹⁶ [i]
