(156, 191, 771680)-Net in Base 3 — Upper bound on s
There is no (156, 191, 771681)-net in base 3, because
- 1 times m-reduction [i] would yield (156, 190, 771681)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 4 498233 503534 683373 854402 624904 570836 154308 517695 538262 031598 240373 714141 145802 118329 947779 > 3190 [i]
