(47, 68, 1405)-Net over F₈ — Digital

Digital (47, 68, 1405)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(47, 68, 727072)-Net in Base 8 — Upper bound on s

There is no (47, 68, 727073)-net in base 8, because

1 times m-reduction [i] would yield (47, 67, 727073)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 3 213904 389788 558769 191614 126082 547635 539053 017428 884712 828656 > 8⁶⁷ [i]
