(120−81, 120, 3995)-Net in Base 16 — Upper bound on s

There is no (39, 120, 3996)-net in base 16, because

1 times m-reduction [i] would yield (39, 119, 3996)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 196332 413070 259410 214794 272250 939586 940711 223168 988513 218137 721006 413380 792571 353347 495808 389230 897458 958150 144445 972202 798897 521754 001522 267476 > 16¹¹⁹ [i]
