(84, 228, 685)-Net in Base 4 — Upper bound on s

There is no (84, 228, 686)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 203585 843304 578858 201257 550373 484999 318430 036401 382404 669004 577342 404345 580651 293701 915169 547875 375199 627851 092683 014878 593994 698782 188078 > 4²²⁸ [i]
