(19, 64, 1682)-Net in Base 16 — Upper bound on s

There is no (19, 64, 1683)-net in base 16, because

1 times m-reduction [i] would yield (19, 63, 1683)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 7322 600566 412827 369554 894643 103265 749242 826244 966889 367164 256215 762109 859616 > 16⁶³ [i]
