(141−51, 141, 1005)-Net over F₈ — Digital

Digital (90, 141, 1005)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(141−51, 141, 165878)-Net in Base 8 — Upper bound on s

There is no (90, 141, 165879)-net in base 8, because

1 times m-reduction [i] would yield (90, 140, 165879)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 2 707756 846962 876707 857060 147528 095486 251861 396763 482330 243655 161586 117714 972881 572978 564179 323542 392725 979874 356359 575255 888088 > 8¹⁴⁰ [i]
