      - a curve from the manYPoints database [i]

(145−81, 145, 3991)-Net in Base 8 — Upper bound on s

There is no (64, 145, 3992)-net in base 8, because

1 times m-reduction [i] would yield (64, 144, 3992)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 11196 137338 721177 088047 318261 734112 244886 968208 656601 233296 702746 419214 399218 732776 112243 373532 980584 990366 915461 637788 221446 033000 > 8¹⁴⁴ [i]
