(25, 25+35, 38747)-Net in Base 32 — Upper bound on s

There is no (25, 60, 38748)-net in base 32, because

1 times m-reduction [i] would yield (25, 59, 38748)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 63671 747377 251981 181957 644916 737193 275103 093583 749623 344381 875712 735439 704122 239148 695143 > 32⁵⁹ [i]
