(72, 72+41, 135354)-Net in Base 8 — Upper bound on s
There is no (72, 113, 135355)-net in base 8, because
- 1 times m-reduction [i] would yield (72, 112, 135355)-net in base 8, but
- the generalized Rao bound for nets shows that 8m ≥ 139995 849745 730099 037518 043734 968859 031155 815805 691428 390332 869613 032124 579563 259464 940580 443564 886866 > 8112 [i]
