(172−103, 172, 2993)-Net in Base 8 — Upper bound on s

There is no (69, 172, 2994)-net in base 8, because

1 times m-reduction [i] would yield (69, 171, 2994)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 27226 969285 278870 938198 404061 715144 477369 331762 053364 541321 798188 663281 399534 980526 979743 213915 798396 434696 225547 525460 351553 608510 136911 258965 333926 086784 > 8¹⁷¹ [i]
