(4, 4+21, 4064)-Net in Base 128 — Upper bound on s
There is no (4, 25, 4065)-net in base 128, because
- 1 times m-reduction [i] would yield (4, 24, 4065)-net in base 128, but
- the generalized Rao bound for nets shows that 128m ≥ 374 772365 346759 127918 718265 601795 183914 028306 318992 > 12824 [i]
