(116, 116+29, 3140161)-Net in Base 4 — Upper bound on s
There is no (116, 145, 3140162)-net in base 4, because
- 1 times m-reduction [i] would yield (116, 144, 3140162)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 497 324194 779615 625161 073265 240907 174037 241918 940501 349130 560566 142345 878533 737431 769312 > 4144 [i]
