(4, 4+27, 3247)-Net in Base 128 — Upper bound on s
There is no (4, 31, 3248)-net in base 128, because
- 1 times m-reduction [i] would yield (4, 30, 3248)-net in base 128, but
- the generalized Rao bound for nets shows that 128m ≥ 1647 288725 393321 269298 475381 956145 304718 081570 806600 857956 583411 > 12830 [i]
