(184, 184+35, 4712942)-Net in Base 3 — Upper bound on s

There is no (184, 219, 4712943)-net in base 3, because

1 times m-reduction [i] would yield (184, 218, 4712943)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 102 904517 979078 117364 937756 179088 177598 896010 754190 472501 410581 581157 100628 246766 520005 066879 303646 151615 > 3²¹⁸ [i]
