MinT - Best Known (166−101, 166, s)-Nets in Base 4

Best Known (166−101, 166, s)-Nets in Base 4

(166−101, 166, 66)-Net over F₄ — Constructive and digital

Digital (65, 166, 66)-net over F₄, using

t-expansion [i] based on digital (49, 166, 66)-net over F₄, using
- net from sequence [i] based on digital (49, 65)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 49 and N(F) ≥ 66, using
    - T₆ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(166−101, 166, 99)-Net over F₄ — Digital

Digital (65, 166, 99)-net over F₄, using

t-expansion [i] based on digital (61, 166, 99)-net over F₄, using
- net from sequence [i] based on digital (61, 98)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 61 and N(F) ≥ 99, using
    - Drinfeld modules of rank 1 [i]

(166−101, 166, 589)-Net in Base 4 — Upper bound on s

There is no (65, 166, 590)-net in base 4, because

1 times m-reduction [i] would yield (65, 165, 590)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2217 886807 023578 262258 310141 710161 598467 843793 702335 052774 544451 221150 185880 369473 470835 264445 310680 > 4¹⁶⁵ [i]
