Best Known (109, 242, s)-Nets in Base 4

(109, 242, 130)-Net over F₄ — Constructive and digital

Digital (109, 242, 130)-net over F₄, using

t-expansion [i] based on digital (105, 242, 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]

(109, 242, 165)-Net over F₄ — Digital

Digital (109, 242, 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]

(109, 242, 1284)-Net in Base 4 — Upper bound on s

There is no (109, 242, 1285)-net in base 4, because

1 times m-reduction [i] would yield (109, 241, 1285)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 019442 550620 318135 288537 102475 902680 052179 594133 088551 029873 168251 540522 507985 425538 646465 384883 110293 865125 962359 626382 941719 318587 038750 317000 > 4²⁴¹ [i]
