(38−15, 38, 521745)-Net in Base 16 — Upper bound on s
There is no (23, 38, 521746)-net in base 16, because
- 1 times m-reduction [i] would yield (23, 37, 521746)-net in base 16, but
- the generalized Rao bound for nets shows that 16m ≥ 356 814400 478288 626052 339354 436448 659941 186056 > 1637 [i]
