Best Known (126−49, 126, s)-Nets in Base 4

(126−49, 126, 130)-Net over F₄ — Constructive and digital

Digital (77, 126, 130)-net over F₄, using

16 times m-reduction [i] based on digital (77, 142, 130)-net over F₄, using
- trace code for nets [i] based on digital (6, 71, 65)-net over F₁₆, using
  - net from sequence [i] based on digital (6, 64)-sequence over F₁₆, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 6 and N(F) ≥ 65, using
      - the Hermitian function field over F₁₆ [i]

(126−49, 126, 218)-Net over F₄ — Digital

Digital (77, 126, 218)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(126−49, 126, 4447)-Net in Base 4 — Upper bound on s

There is no (77, 126, 4448)-net in base 4, because

1 times m-reduction [i] would yield (77, 125, 4448)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1818 350131 527320 112645 695998 712795 675848 379982 948195 277112 324869 507186 896451 > 4¹²⁵ [i]
