(61−39, 61, 63611)-Net in Base 64 — Upper bound on s

There is no (22, 61, 63612)-net in base 64, because

1 times m-reduction [i] would yield (22, 60, 63612)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 2 348682 050008 993872 473572 337552 627512 951239 051135 437216 564534 477308 290808 779342 427956 533706 389545 476353 408815 > 64⁶⁰ [i]
