Best Known (80, 80+61, s)-Nets in Base 4

(80, 80+61, 130)-Net over F₄ — Constructive and digital

Digital (80, 141, 130)-net over F₄, using

7 times m-reduction [i] based on digital (80, 148, 130)-net over F₄, using
- trace code for nets [i] based on digital (6, 74, 65)-net over F₁₆, using
  - net from sequence [i] based on digital (6, 64)-sequence over F₁₆, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 6 and N(F) ≥ 65, using
      - the Hermitian function field over F₁₆ [i]

(80, 80+61, 168)-Net over F₄ — Digital

Digital (80, 141, 168)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(80, 80+61, 2565)-Net in Base 4 — Upper bound on s

There is no (80, 141, 2566)-net in base 4, because

1 times m-reduction [i] would yield (80, 140, 2566)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 954517 636698 037572 905506 708881 402759 381967 492656 903458 607044 613573 540902 659260 076800 > 4¹⁴⁰ [i]
