(104, 145, 3770983)-Net in Base 8 — Upper bound on s
There is no (104, 145, 3770984)-net in base 8, because
- 1 times m-reduction [i] would yield (104, 144, 3770984)-net in base 8, but
- the generalized Rao bound for nets shows that 8m ≥ 11090 686792 968889 262220 610871 560373 293025 686578 646021 468746 654210 779483 218983 107260 310075 788038 790504 857495 256182 703565 249109 426782 > 8144 [i]
