(197−110, 197, 975)-Net in Base 4 — Upper bound on s

There is no (87, 197, 976)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 42130 976407 287094 053365 293146 522817 120956 389714 888689 424890 213491 343871 738688 406200 816974 905291 963003 248811 405950 745324 > 4¹⁹⁷ [i]
