(144−33, 144, 62470)-Net in Base 3 — Upper bound on s
There is no (111, 144, 62471)-net in base 3, because
- 1 times m-reduction [i] would yield (111, 143, 62471)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 169 215192 152797 955341 359954 503246 186478 329793 634911 671218 806423 288033 > 3143 [i]
