(130, 157, 1506009)-Net in Base 3 — Upper bound on s
There is no (130, 157, 1506010)-net in base 3, because
- 1 times m-reduction [i] would yield (130, 156, 1506010)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 269 723390 791506 168465 075223 312939 216441 728155 291825 349367 154741 663046 565821 > 3156 [i]
