Best Known (108−47, 108, s)-Nets in Base 4

(108−47, 108, 130)-Net over F₄ — Constructive and digital

Digital (61, 108, 130)-net over F₄, using

2 times m-reduction [i] based on digital (61, 110, 130)-net over F₄, using
- trace code for nets [i] based on digital (6, 55, 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]

(108−47, 108, 132)-Net over F₄ — Digital

Digital (61, 108, 132)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(108−47, 108, 1968)-Net in Base 4 — Upper bound on s

There is no (61, 108, 1969)-net in base 4, because

1 times m-reduction [i] would yield (61, 107, 1969)-net in base 4, but
