Best Known (85, 246, s)-Nets in Base 4

(85, 246, 104)-Net over F₄ — Constructive and digital

Digital (85, 246, 104)-net over F₄, using

t-expansion [i] based on digital (73, 246, 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]

(85, 246, 129)-Net over F₄ — Digital

Digital (85, 246, 129)-net over F₄, using

t-expansion [i] based on digital (81, 246, 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]

(85, 246, 647)-Net in Base 4 — Upper bound on s

There is no (85, 246, 648)-net in base 4, because

1 times m-reduction [i] would yield (85, 245, 648)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3235 497863 721126 471532 568601 837837 134559 749979 778209 682964 318665 516237 810435 409448 062687 609346 183034 325506 983573 157372 334055 613375 275622 395459 333064 > 4²⁴⁵ [i]
