(247−152, 247, 446)-Net in Base 3 — Upper bound on s

There is no (95, 247, 447)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 8093 830686 573018 714214 016795 818778 429497 218294 469355 350039 020074 950670 576747 324151 240662 498203 574511 158009 189875 280745 > 3²⁴⁷ [i]
