(18, 63, 1481)-Net in Base 16 — Upper bound on s

There is no (18, 63, 1482)-net in base 16, because

1 times m-reduction [i] would yield (18, 62, 1482)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 455 601298 748246 912245 682588 624918 606911 556563 262217 844644 059018 394465 918736 > 16⁶² [i]
