(13, 13+33, 12966)-Net in Base 64 — Upper bound on s

There is no (13, 46, 12967)-net in base 64, because

1 times m-reduction [i] would yield (13, 45, 12967)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 1898 518269 772751 387793 877068 549553 059590 176232 386841 294463 507929 849521 174391 223574 > 64⁴⁵ [i]
