(121−91, 121, 1885)-Net in Base 16 — Upper bound on s

There is no (30, 121, 1886)-net in base 16, because

1 times m-reduction [i] would yield (30, 120, 1886)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 3 178343 064583 599301 406912 073096 986163 852725 827220 782179 803934 083725 907980 107411 987281 585872 542269 395724 610982 172706 025663 988299 188153 297829 606426 > 16¹²⁰ [i]
