Best Known (42−24, 42, s)-Nets in Base 4

(42−24, 42, 33)-Net over F₄ — Constructive and digital

Digital (18, 42, 33)-net over F₄, using

t-expansion [i] based on digital (15, 42, 33)-net over F₄, using
- net from sequence [i] based on digital (15, 32)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 15 and N(F) ≥ 33, using
    - an explicitly constructive algebraic function field [i]

(42−24, 42, 41)-Net over F₄ — Digital

Digital (18, 42, 41)-net over F₄, using

net from sequence [i] based on digital (18, 40)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 18 and N(F) ≥ 41, using
  - Drinfeld modules of rank 1 [i]

(42−24, 42, 216)-Net in Base 4 — Upper bound on s

There is no (18, 42, 217)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 20 064047 460334 582543 062220 > 4⁴² [i]
