(28, 28+97, 1585)-Net in Base 16 — Upper bound on s

There is no (28, 125, 1586)-net in base 16, because

1 times m-reduction [i] would yield (28, 124, 1586)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 208755 724751 009593 123295 334866 300339 133077 319985 528241 083128 128502 176389 953861 429282 427384 194565 850760 114149 239818 877559 439440 181148 404718 192666 146721 > 16¹²⁴ [i]
