(246−89, 246, 12911)-Net in Base 4 — Upper bound on s
There is no (157, 246, 12912)-net in base 4, because
- 1 times m-reduction [i] would yield (157, 245, 12912)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 3205 111898 704953 364906 846134 940336 372554 074216 357920 737750 404145 914336 551531 934043 606098 134002 285343 486320 066447 129966 619140 303697 916795 292122 274385 > 4245 [i]
