Best Known (98, 155, s)-Nets in Base 4

(98, 155, 139)-Net over F₄ — Constructive and digital

Digital (98, 155, 139)-net over F₄, using

(u,Â u+v)-construction [i] based on
1. digital (1, 29, 9)-net over F₄, using
  - net from sequence [i] based on digital (1, 8)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 1 and N(F) ≥ 9, using
      - the Hermitian function field over F₄ [i]
2. digital (69, 126, 130)-net over F₄, using
  - trace code for nets [i] based on digital (6, 63, 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]

(98, 155, 313)-Net over F₄ — Digital

Digital (98, 155, 313)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(98, 155, 7690)-Net in Base 4 — Upper bound on s

There is no (98, 155, 7691)-net in base 4, because

1 times m-reduction [i] would yield (98, 154, 7691)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 523 335753 851643 557133 349670 547909 019190 046186 516480 091384 579882 784564 565544 780101 008908 758400 > 4¹⁵⁴ [i]
