(140, 250, 1519)-Net in Base 3 — Upper bound on s

There is no (140, 250, 1520)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 192351 098855 709173 568329 696006 753356 066348 691279 451375 595098 513233 324817 745574 167327 663843 830138 147663 111218 019212 388161 > 3²⁵⁰ [i]
