Best Known (148−39, 148, s)-Nets in Base 4

(148−39, 148, 531)-Net over F₄ — Constructive and digital

Digital (109, 148, 531)-net over F₄, using

5 times m-reduction [i] based on digital (109, 153, 531)-net over F₄, using
- trace code for nets [i] based on digital (7, 51, 177)-net over F₆₄, using
  - net from sequence [i] based on digital (7, 176)-sequence over F₆₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 7 and N(F) ≥ 177, using
      - a function field by GarcÃa and Quoos [i]

Digital (109, 148, 1127)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(148−39, 148, 120249)-Net in Base 4 — Upper bound on s

There is no (109, 148, 120250)-net in base 4, because

1 times m-reduction [i] would yield (109, 147, 120250)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 31833 023788 329535 154641 837335 325897 059756 215922 976024 620995 619121 996546 851500 735441 916076 > 4¹⁴⁷ [i]
