Best Known (89, 89+121, s)-Nets in Base 4

(89, 89+121, 104)-Net over F₄ — Constructive and digital

Digital (89, 210, 104)-net over F₄, using

t-expansion [i] based on digital (73, 210, 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]

(89, 89+121, 129)-Net over F₄ — Digital

Digital (89, 210, 129)-net over F₄, using

t-expansion [i] based on digital (81, 210, 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]

(89, 89+121, 918)-Net in Base 4 — Upper bound on s

There is no (89, 210, 919)-net in base 4, because

1 times m-reduction [i] would yield (89, 209, 919)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 704230 828585 631404 456874 141085 659519 639309 156098 882901 661324 662877 199452 370251 886348 507166 519368 422379 134458 482578 101138 205520 > 4²⁰⁹ [i]
