(254−156, 254, 846)-Net in Base 4 — Upper bound on s

There is no (98, 254, 847)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 911 816507 192724 830761 824676 465725 198671 715205 027318 151397 918762 713162 104771 809327 614757 944154 916039 073904 334104 352723 436485 027726 642530 812884 995457 335421 > 4²⁵⁴ [i]
