Best Known (137, 180, s)-Nets in Base 4

(137, 180, 1036)-Net over F₄ — Constructive and digital

Digital (137, 180, 1036)-net over F₄, using

trace code for nets [i] based on digital (2, 45, 259)-net over F₂₅₆, using
- net from sequence [i] based on digital (2, 258)-sequence over F₂₅₆, using
  - Niederreiter sequence [i]

(137, 180, 2115)-Net over F₄ — Digital

Digital (137, 180, 2115)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(137, 180, 391919)-Net in Base 4 — Upper bound on s

There is no (137, 180, 391920)-net in base 4, because

1 times m-reduction [i] would yield (137, 179, 391920)-net in base 4, but
