(14, 14+33, 16817)-Net in Base 64 — Upper bound on s

There is no (14, 47, 16818)-net in base 64, because

1 times m-reduction [i] would yield (14, 46, 16818)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 121456 688750 701451 698121 827890 937833 416703 787285 969633 418775 166743 654221 110984 315495 > 64⁴⁶ [i]
