(142−57, 142, 601)-Net over F₈ — Digital

Digital (85, 142, 601)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(142−57, 142, 56947)-Net in Base 8 — Upper bound on s

There is no (85, 142, 56948)-net in base 8, because

1 times m-reduction [i] would yield (85, 141, 56948)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 21 663944 108124 414109 446636 063829 965238 869376 296855 305186 827472 855010 850425 576363 403869 244783 556792 164401 723816 318459 467798 660232 > 8¹⁴¹ [i]
