        a function field by SÃ©mirat [i]

(26, 26+49, 425)-Net over F₆₄ — Digital

Digital (26, 75, 425)-net over F₆₄, using

net from sequence [i] based on digital (26, 424)-sequence over F₆₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 26 and N(F) ≥ 425, using

(26, 26+49, 57675)-Net in Base 64 — Upper bound on s

There is no (26, 75, 57676)-net in base 64, because

1 times m-reduction [i] would yield (26, 74, 57676)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 45 446192 055503 580943 345569 500024 138730 297692 752644 682130 619616 686899 656889 239685 266724 964530 696736 330020 727138 094048 532883 147176 239876 > 64⁷⁴ [i]
