(146−47, 146, 1913)-Net over F₈ — Digital

Digital (99, 146, 1913)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(146−47, 146, 664878)-Net in Base 8 — Upper bound on s

There is no (99, 146, 664879)-net in base 8, because

1 times m-reduction [i] would yield (99, 145, 664879)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 88726 894114 236128 660066 146572 680415 145241 119548 472756 582705 587953 819599 404067 594600 557423 374929 672031 450665 496983 608679 422227 645280 > 8¹⁴⁵ [i]
