(20, 20+49, 492)-Net in Base 8 — Upper bound on s
There is no (20, 69, 493)-net in base 8, because
- 1 times m-reduction [i] would yield (20, 68, 493)-net in base 8, but
- the generalized Rao bound for nets shows that 8m ≥ 26 678053 681948 995200 913949 419543 794230 569534 703786 276571 938762 > 868 [i]
