(115−77, 115, 4081)-Net in Base 16 — Upper bound on s

There is no (38, 115, 4082)-net in base 16, because

1 times m-reduction [i] would yield (38, 114, 4082)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 186565 487296 283895 487321 395203 204031 806282 881299 136159 941093 203117 882862 542711 342343 371384 655982 743529 895588 599558 592427 155211 039532 821016 > 16¹¹⁴ [i]
