(85, 85+120, 833)-Net in Base 4 — Upper bound on s

There is no (85, 205, 834)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2812 440640 570485 284353 150719 327653 735160 726134 632884 136509 175272 734641 340352 364044 200472 989375 803839 962077 417748 562355 886320 > 4²⁰⁵ [i]
