(209−124, 209, 803)-Net in Base 4 — Upper bound on s

There is no (85, 209, 804)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 683911 159821 516055 614266 339094 011959 874712 502165 262937 179004 092861 967682 163874 063726 561823 423273 810266 991755 855437 318489 024320 > 4²⁰⁹ [i]
