(66−43, 66, 53656)-Net in Base 64 — Upper bound on s

There is no (23, 66, 53657)-net in base 64, because

1 times m-reduction [i] would yield (23, 65, 53657)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 2521 842149 816550 741053 853243 645519 135239 489831 197930 294437 347624 400017 926233 951352 116318 692345 393909 060115 182952 409048 > 64⁶⁵ [i]
