(15, 50, 18300)-Net in Base 64 — Upper bound on s

There is no (15, 50, 18301)-net in base 64, because

1 times m-reduction [i] would yield (15, 49, 18301)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 31851 357286 939171 213597 729217 961545 051640 319012 858748 872007 280269 218606 753622 283689 556244 > 64⁴⁹ [i]
