Best Known (99, 99+147, s)-Nets in Base 4

(99, 99+147, 104)-Net over F₄ — Constructive and digital

Digital (99, 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]

(99, 99+147, 144)-Net over F₄ — Digital

Digital (99, 246, 144)-net over F₄, using

t-expansion [i] based on digital (91, 246, 144)-net over F₄, using
- net from sequence [i] based on digital (91, 143)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 91 and N(F) ≥ 144, using
    - Drinfeld modules of rank 1 [i]

(99, 99+147, 919)-Net in Base 4 — Upper bound on s

There is no (99, 246, 920)-net in base 4, because

1 times m-reduction [i] would yield (99, 245, 920)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3201 374677 990880 795727 448989 775078 102923 620165 117124 209981 026504 675563 542176 972073 953114 905283 244534 016354 579825 797752 413553 859520 877596 967647 647620 > 4²⁴⁵ [i]
