(25, 25+93, 1360)-Net in Base 16 — Upper bound on s

There is no (25, 118, 1361)-net in base 16, because

1 times m-reduction [i] would yield (25, 117, 1361)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 771 314134 177913 836434 506901 794258 097871 974804 984978 711968 597384 085306 968553 522875 087742 717205 155933 070997 058313 905594 363781 221905 334352 963216 > 16¹¹⁷ [i]
