(28, 121, 1635)-Net in Base 16 — Upper bound on s

There is no (28, 121, 1636)-net in base 16, because

1 times m-reduction [i] would yield (28, 120, 1636)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 3 178927 209418 485450 869863 084035 435838 264472 758613 492434 719001 913147 411520 593233 184104 960624 539705 595297 042422 673861 261548 055083 557794 375963 159216 > 16¹²⁰ [i]
