(93, 93+47, 1464)-Net over F₈ — Digital

Digital (93, 140, 1464)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(93, 93+47, 386497)-Net in Base 8 — Upper bound on s

There is no (93, 140, 386498)-net in base 8, because

1 times m-reduction [i] would yield (93, 139, 386498)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 338467 097047 048607 913538 658416 071554 884426 903818 579847 475145 684646 118802 440576 583277 457614 681066 270862 273993 386959 887331 786976 > 8¹³⁹ [i]
