Best Known (24, 24+37, s)-Nets in Base 4

(24, 24+37, 34)-Net over F₄ — Constructive and digital

Digital (24, 61, 34)-net over F₄, using

t-expansion [i] based on digital (21, 61, 34)-net over F₄, using
- net from sequence [i] based on digital (21, 33)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 21 and N(F) ≥ 34, using
    - T₅ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(24, 24+37, 35)-Net in Base 4 — Constructive

(24, 61, 35)-net in base 4, using

net from sequence [i] based on (24, 34)-sequence in base 4, using
- base expansion [i] based on digital (48, 34)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 41, N(F)Â =Â 32, 1 place with degree 2, and 2 places with degree 4 [i] based on function field F/F₂ with g(F) = 41 and N(F) ≥ 32, using an explicitly constructive algebraic function field [i]

(24, 24+37, 49)-Net over F₄ — Digital

Digital (24, 61, 49)-net over F₄, using

net from sequence [i] based on digital (24, 48)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 24 and N(F) ≥ 49, using
  - a curve from the manYPoints database [i]

(24, 24+37, 241)-Net in Base 4 — Upper bound on s

There is no (24, 61, 242)-net in base 4, because

1 times m-reduction [i] would yield (24, 60, 242)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 367682 585355 386272 008149 729040 644616 > 4⁶⁰ [i]
