(13, 13+23, 43506)-Net in Base 64 — Upper bound on s

There is no (13, 36, 43507)-net in base 64, because

1 times m-reduction [i] would yield (13, 35, 43507)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 1645 542050 627198 532416 521768 308445 467118 768289 681149 496405 512720 > 64³⁵ [i]
