(176−41, 176, 513093)-Net in Base 4 — Upper bound on s
There is no (135, 176, 513094)-net in base 4, because
- 1 times m-reduction [i] would yield (135, 175, 513094)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 2293 574595 469550 627703 943867 667444 287207 109286 304526 152859 577765 351704 967120 326330 410255 820572 759220 902204 > 4175 [i]
