(46, 91, 419673)-Net in Base 32 — Upper bound on s

There is no (46, 91, 419674)-net in base 32, because

1 times m-reduction [i] would yield (46, 90, 419674)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 2907 443508 449008 874898 749594 698442 031013 047834 733997 936283 170525 680197 139888 839734 455485 994719 259069 141912 196345 061084 986535 179047 831404 > 32⁹⁰ [i]
