(231−120, 231, 738)-Net in Base 3 — Upper bound on s

There is no (111, 231, 739)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 165 957653 752799 091404 968435 582975 567785 917718 613684 734618 949934 946723 975286 088326 158081 018233 124981 502873 314537 > 3²³¹ [i]
