(147−39, 147, 465774)-Net in Base 5 — Upper bound on s
There is no (108, 147, 465775)-net in base 5, because
- 1 times m-reduction [i] would yield (108, 146, 465775)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 1 121078 738824 767469 061596 991183 176754 199408 490268 740718 032512 051134 830453 709929 096097 564010 309113 775221 > 5146 [i]
