(92−25, 92, 5329607)-Net in Base 8 — Upper bound on s

There is no (67, 92, 5329608)-net in base 8, because

1 times m-reduction [i] would yield (67, 91, 5329608)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 15177 134311 445047 187690 565965 486789 907278 352851 605351 460882 962784 656117 952616 023592 > 8⁹¹ [i]
