(27, 58, 609)-Net over F₆₄ — Digital

Digital (27, 58, 609)-net over F₆₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(27, 58, 744570)-Net in Base 64 — Upper bound on s

There is no (27, 58, 744571)-net in base 64, because

1 times m-reduction [i] would yield (27, 57, 744571)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 8 959086 168924 072379 492352 076307 512093 938272 050891 737638 009027 080751 971096 965277 771862 678443 809191 541776 > 64⁵⁷ [i]
