(105, 105+142, 555)-Net in Base 3 — Upper bound on s

There is no (105, 247, 556)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 7421 951929 558862 166356 264642 597482 498488 667894 047848 801272 799143 602044 411406 606925 030077 540739 527909 197264 356088 574417 > 3²⁴⁷ [i]
