Best Known (82, 82+169, s)-Nets in Base 4

(82, 82+169, 104)-Net over F₄ — Constructive and digital

Digital (82, 251, 104)-net over F₄, using

t-expansion [i] based on digital (73, 251, 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+169, 129)-Net over F₄ — Digital

Digital (82, 251, 129)-net over F₄, using

t-expansion [i] based on digital (81, 251, 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+169, 595)-Net in Base 4 — Upper bound on s

There is no (82, 251, 596)-net in base 4, because

1 times m-reduction [i] would yield (82, 250, 596)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 610105 727518 787786 114108 495462 369494 918020 115213 480764 072823 331865 422998 813947 904193 998961 532446 069754 758199 300047 788142 856631 742249 406243 499837 479952 > 4²⁵⁰ [i]
