(141−35, 141, 30472)-Net in Base 3 — Upper bound on s
There is no (106, 141, 30473)-net in base 3, because
- 1 times m-reduction [i] would yield (106, 140, 30473)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 6 266075 835322 804712 683098 495247 120965 146171 363351 658631 646817 499347 > 3140 [i]
