(99, 99+33, 898028)-Net in Base 5 — Upper bound on s

There is no (99, 132, 898029)-net in base 5, because

1 times m-reduction [i] would yield (99, 131, 898029)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 36 734576 307843 771170 906054 763306 526929 305946 961956 961859 892618 995524 767981 750606 862030 995905 > 5¹³¹ [i]
