(38, 38+43, 22351)-Net in Base 16 — Upper bound on s

There is no (38, 81, 22352)-net in base 16, because

1 times m-reduction [i] would yield (38, 80, 22352)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 2 137304 450779 462175 020354 326451 357012 645396 777474 584879 831053 947137 835297 228614 312246 509889 190756 > 16⁸⁰ [i]
