(44, 71, 59025)-Net in Base 8 — Upper bound on s

There is no (44, 71, 59026)-net in base 8, because

1 times m-reduction [i] would yield (44, 70, 59026)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 1645 543062 097734 350805 755329 296524 851445 663098 549178 022168 693588 > 8⁷⁰ [i]
