MinT - Best Known (121−81, 121, s)-Nets in Base 5

Best Known (121−81, 121, s)-Nets in Base 5

(121−81, 121, 78)-Net over F₅ — Constructive and digital

Digital (40, 121, 78)-net over F₅, using

t-expansion [i] based on digital (38, 121, 78)-net over F₅, using
- net from sequence [i] based on digital (38, 77)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 38 and N(F) ≥ 78, using
    - an explicitly constructive algebraic function field [i]

(121−81, 121, 463)-Net in Base 5 — Upper bound on s

There is no (40, 121, 464)-net in base 5, because

1 times m-reduction [i] would yield (40, 120, 464)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 759796 172779 706104 274562 640572 337502 418752 983085 799137 710230 505705 127840 288863 299585 > 5¹²⁰ [i]
