(48−33, 48, 21812)-Net in Base 64 — Upper bound on s

There is no (15, 48, 21813)-net in base 64, because

1 times m-reduction [i] would yield (15, 47, 21813)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 7 775799 538132 714521 912749 326595 995387 586311 613004 889142 464218 662293 974422 527769 429395 > 64⁴⁷ [i]
