(26, 57, 532)-Net over F₆₄ — Digital

Digital (26, 57, 532)-net over F₆₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(26, 57, 564277)-Net in Base 64 — Upper bound on s

There is no (26, 57, 564278)-net in base 64, because

1 times m-reduction [i] would yield (26, 56, 564278)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 139987 406388 991827 501216 753943 788667 732233 037492 042862 726077 099295 177944 401286 109173 252812 340508 086264 > 64⁵⁶ [i]
