Best Known (31−22, 31, s)-Nets in Base 4

(31−22, 31, 22)-Net over F₄ — Constructive and digital

Digital (9, 31, 22)-net over F₄, using

net from sequence [i] based on digital (9, 21)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 9 and N(F) ≥ 22, using
  - an explicitly constructive algebraic function field [i]

(31−22, 31, 26)-Net over F₄ — Digital

Digital (9, 31, 26)-net over F₄, using

net from sequence [i] based on digital (9, 25)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 9 and N(F) ≥ 26, using
  - Drinfeld modules of rank 1 [i]

(31−22, 31, 73)-Net in Base 4 — Upper bound on s

There is no (9, 31, 74)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 5 224710 458208 710128 > 4³¹ [i]
