Best Known (77, 218, s)-Nets in Base 4

(77, 218, 104)-Net over F₄ — Constructive and digital

Digital (77, 218, 104)-net over F₄, using

t-expansion [i] based on digital (73, 218, 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]

(77, 218, 112)-Net over F₄ — Digital

Digital (77, 218, 112)-net over F₄, using

t-expansion [i] based on digital (73, 218, 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]

(77, 218, 603)-Net in Base 4 — Upper bound on s

There is no (77, 218, 604)-net in base 4, because

1 times m-reduction [i] would yield (77, 217, 604)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 48686 072324 390265 991868 993473 538356 837646 861857 350151 875202 967642 347180 964676 092317 431625 949322 813374 348736 884317 532047 740572 559106 > 4²¹⁷ [i]
