(98, 98+31, 37844)-Net in Base 3 — Upper bound on s
There is no (98, 129, 37845)-net in base 3, because
- 1 times m-reduction [i] would yield (98, 128, 37845)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 11 791608 037427 732204 629455 678009 564286 326886 316751 690870 846395 > 3128 [i]
