(25, 25+99, 1315)-Net in Base 16 — Upper bound on s

There is no (25, 124, 1316)-net in base 16, because

1 times m-reduction [i] would yield (25, 123, 1316)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 13248 395735 220147 480446 882317 327214 350765 363990 316308 381298 699370 226860 107359 894375 276581 874369 643766 382373 565921 627425 650419 696478 136644 462612 350736 > 16¹²³ [i]
