(19, 46, 29654)-Net in Base 32 — Upper bound on s

There is no (19, 46, 29655)-net in base 32, because

1 times m-reduction [i] would yield (19, 45, 29655)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 53 940717 484897 386297 548370 053347 280909 180660 595005 321438 389774 641764 > 32⁴⁵ [i]
