(25, 25+41, 20867)-Net in Base 32 — Upper bound on s

There is no (25, 66, 20868)-net in base 32, because

1 times m-reduction [i] would yield (25, 65, 20868)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 68 382828 248451 222484 783412 786264 482175 779528 941571 298543 108148 651793 688801 321406 838206 818641 684192 > 32⁶⁵ [i]
