(81, 191, 832)-Net in Base 4 — Upper bound on s

There is no (81, 191, 833)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10 364191 661715 367452 565616 615295 021549 825657 161082 699610 946885 185757 836164 425367 242562 934894 549217 863171 156543 074880 > 4¹⁹¹ [i]
