(231−130, 231, 559)-Net in Base 3 — Upper bound on s

There is no (101, 231, 560)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 174 075293 806504 284235 186788 369230 344014 588966 858201 508122 340874 520772 912819 696837 558412 398840 642571 307142 876257 > 3²³¹ [i]
