      - a curve from the manYPoints database [i]

(142−79, 142, 4024)-Net in Base 8 — Upper bound on s

There is no (63, 142, 4025)-net in base 8, because

1 times m-reduction [i] would yield (63, 141, 4025)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 21 777202 349566 003331 396372 060046 427107 941467 826392 515657 050005 131078 976058 376257 703907 287800 010983 512121 524815 511846 042014 218968 > 8¹⁴¹ [i]
