MinT - Best Known (260−151, 260, s)-Nets in Base 4

Best Known (260−151, 260, s)-Nets in Base 4

(260−151, 260, 130)-Net over F₄ — Constructive and digital

Digital (109, 260, 130)-net over F₄, using

t-expansion [i] based on digital (105, 260, 130)-net over F₄, using
- net from sequence [i] based on digital (105, 129)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 105 and N(F) ≥ 130, using
    - T₇ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(260−151, 260, 165)-Net over F₄ — Digital

Digital (109, 260, 165)-net over F₄, using

net from sequence [i] based on digital (109, 164)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 109 and N(F) ≥ 165, using
  - Drinfeld modules of rank 1 [i]

(260−151, 260, 1088)-Net in Base 4 — Upper bound on s

There is no (109, 260, 1089)-net in base 4, because

1 times m-reduction [i] would yield (109, 259, 1089)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 861007 719442 308298 848583 484070 470876 419413 125187 372863 260928 251688 814176 997413 093429 309510 437702 512731 407340 117713 521369 661375 125901 999712 678557 807456 832512 > 4²⁵⁹ [i]
