MinT - Best Known (114−65, 114, s)-Nets in Base 4

Best Known (114−65, 114, s)-Nets in Base 4

(114−65, 114, 66)-Net over F₄ — Constructive and digital

Digital (49, 114, 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]

(114−65, 114, 81)-Net over F₄ — Digital

Digital (49, 114, 81)-net over F₄, using

t-expansion [i] based on digital (46, 114, 81)-net over F₄, using
- net from sequence [i] based on digital (46, 80)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 46 and N(F) ≥ 81, using
    - Drinfeld modules of rank 1 [i]

(114−65, 114, 544)-Net in Base 4 — Upper bound on s

There is no (49, 114, 545)-net in base 4, because

1 times m-reduction [i] would yield (49, 113, 545)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 113 022008 231355 756680 905697 174041 678137 158148 994697 544409 609196 518321 > 4¹¹³ [i]
