(106, 131, 390060)-Net in Base 3 — Upper bound on s
There is no (106, 131, 390061)-net in base 3, because
- 1 times m-reduction [i] would yield (106, 130, 390061)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 106 112607 614702 737203 461828 591742 196038 010090 926710 370386 153073 > 3130 [i]
