Best Known (15, 56, s)-Nets in Base 256

(15, 56, 272)-Net over F₂₅₆ — Constructive and digital

Digital (15, 56, 272)-net over F₂₅₆, using

net from sequence [i] based on digital (15, 271)-sequence over F₂₅₆, using
- Niederreiter sequence [i]

(15, 56, 513)-Net over F₂₅₆ — Digital

Digital (15, 56, 513)-net over F₂₅₆, using

t-expansion [i] based on digital (8, 56, 513)-net over F₂₅₆, using
- net from sequence [i] based on digital (8, 512)-sequence over F₂₅₆, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅₆ with g(F) = 8 and N(F) ≥ 513, using
    - K_1,1 from the tower of function fields by Niederreiter and Xing based on the tower by GarcÃa and Stichtenoth over F₂₅₆ [i]

(15, 56, 136582)-Net in Base 256 — Upper bound on s

There is no (15, 56, 136583)-net in base 256, because

1 times m-reduction [i] would yield (15, 55, 136583)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 2 839363 843080 260766 807720 511681 626463 428013 414343 765742 117993 563334 100795 122233 240955 703444 215517 260825 557217 694527 932280 075669 341176 > 256⁵⁵ [i]
