Best Known (167−89, 167, s)-Nets in Base 4

(167−89, 167, 104)-Net over F₄ — Constructive and digital

Digital (78, 167, 104)-net over F₄, using

t-expansion [i] based on digital (73, 167, 104)-net over F₄, using
- net from sequence [i] based on digital (73, 103)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 104, using
    - F₆ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(167−89, 167, 112)-Net over F₄ — Digital

Digital (78, 167, 112)-net over F₄, using

t-expansion [i] based on digital (73, 167, 112)-net over F₄, using
- net from sequence [i] based on digital (73, 111)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 112, using
    - Drinfeld modules of rank 1 [i]

(167−89, 167, 1038)-Net in Base 4 — Upper bound on s

There is no (78, 167, 1039)-net in base 4, because

1 times m-reduction [i] would yield (78, 166, 1039)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 8821 222635 641950 136679 385743 534753 942452 836769 424195 912983 728274 153287 077931 619198 867865 769122 426400 > 4¹⁶⁶ [i]
