(64, 97, 7606184)-Net in Base 16 — Upper bound on s
There is no (64, 97, 7606185)-net in base 16, because
- 1 times m-reduction [i] would yield (64, 96, 7606185)-net in base 16, but
- the generalized Rao bound for nets shows that 16m ≥ 39 402023 461684 377686 922446 588952 510028 832744 090129 487434 205908 335062 896316 421149 298604 200285 910505 697563 543247 610026 > 1696 [i]
