(25, 25+91, 1378)-Net in Base 16 — Upper bound on s

There is no (25, 116, 1379)-net in base 16, because

1 times m-reduction [i] would yield (25, 115, 1379)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 2 994251 974011 528518 708367 407281 237801 150293 052325 350192 855284 902834 492117 391223 987136 341963 279924 005905 310002 095430 459557 212112 088454 364576 > 16¹¹⁵ [i]
