(256−160, 256, 796)-Net in Base 4 — Upper bound on s

There is no (96, 256, 797)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13410 519671 658586 556998 237835 842384 947767 344619 001752 124610 770635 611018 418968 891826 946091 455271 971600 039281 976696 415580 450403 378299 384818 765686 793835 757868 > 4²⁵⁶ [i]
