(146−49, 146, 1519)-Net over F₈ — Digital

Digital (97, 146, 1519)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(146−49, 146, 400329)-Net in Base 8 — Upper bound on s

There is no (97, 146, 400330)-net in base 8, because

1 times m-reduction [i] would yield (97, 145, 400330)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 88730 154762 751208 688170 020585 263069 532842 558933 337944 895742 647444 253155 396901 464769 675831 025837 709186 599117 783032 539349 967900 036316 > 8¹⁴⁵ [i]
