(17, 17+49, 267)-Net over F₆₄ — Digital

Digital (17, 66, 267)-net over F₆₄, using

t-expansion [i] based on digital (16, 66, 267)-net over F₆₄, using
- net from sequence [i] based on digital (16, 266)-sequence over F₆₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 16 and N(F) ≥ 267, using

(17, 17+49, 12115)-Net in Base 64 — Upper bound on s

There is no (17, 66, 12116)-net in base 64, because

1 times m-reduction [i] would yield (17, 65, 12116)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 2525 246105 768433 439699 195358 030836 505950 195182 161417 483648 342128 587511 346352 813379 727508 021616 460791 382627 904350 402344 > 64⁶⁵ [i]
