(249−82, 249, 6335)-Net in Base 3 — Upper bound on s

There is no (167, 249, 6336)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 63882 061849 189262 555161 965050 922819 140305 401974 524534 226957 089434 136898 788315 260373 395838 799989 493758 247968 641727 819137 > 3²⁴⁹ [i]
