MinT - Best Known (115−55, 115, s)-Nets in Base 4

Best Known (115−55, 115, s)-Nets in Base 4

(115−55, 115, 66)-Net over F₄ — Constructive and digital

Digital (60, 115, 66)-net over F₄, using

t-expansion [i] based on digital (49, 115, 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]

(115−55, 115, 103)-Net over F₄ — Digital

Digital (60, 115, 103)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(115−55, 115, 1246)-Net in Base 4 — Upper bound on s

There is no (60, 115, 1247)-net in base 4, because

1 times m-reduction [i] would yield (60, 114, 1247)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 433 920421 402564 122384 987403 227254 890982 017971 664760 268651 826411 131760 > 4¹¹⁴ [i]
