Best Known (48, 48+83, s)-Nets in Base 4

(48, 48+83, 56)-Net over F₄ — Constructive and digital

Digital (48, 131, 56)-net over F₄, using

t-expansion [i] based on digital (33, 131, 56)-net over F₄, using
- net from sequence [i] based on digital (33, 55)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 33 and N(F) ≥ 56, using
    - F₅ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(48, 48+83, 81)-Net over F₄ — Digital

Digital (48, 131, 81)-net over F₄, using

t-expansion [i] based on digital (46, 131, 81)-net over F₄, using
- net from sequence [i] based on digital (46, 80)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 46 and N(F) ≥ 81, using
    - Drinfeld modules of rank 1 [i]

(48, 48+83, 403)-Net in Base 4 — Upper bound on s

There is no (48, 131, 404)-net in base 4, because

1 times m-reduction [i] would yield (48, 130, 404)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 929655 505587 547995 906575 592113 617107 753167 003843 880449 551222 103433 997217 657784 > 4¹³⁰ [i]
